Paid user locked out for weeks

Paid user locked out for weeks – no resolution

I am a paying Proton customer (CHF 119 for Lumo Plus + CHF 48 for Mail), and I have been locked out of my account for over 4 weeks with no resolution.

My account appears to be blocked due to a “dispute”, and at the same time it is scheduled for deletion. Even when using my correct 12-word recovery phrase, access is denied.

Support keeps asking standard ownership verification questions, but does not clearly explain:

* what the dispute actually is
* how it can be resolved
* how I can regain access to services I have already paid for

This is not just an account recovery issue — it is also a billing issue involving paid services that are currently inaccessible.

I understand Proton’s strong security model, but in this case the process is opaque and extremely slow. Waiting over 4 weeks without a clear resolution path is not acceptable for a paid service.

Ticket reference: 4539397

I would appreciate a clear explanation and a concrete path to resolution.

Bisher zufrieden,, ABER

Bisher war ich mit dem bezahlten Account zufriedden, diesen werde ich nun aber kündigen, da Proton Nutzerdaten ohne Gerichtsurteil an ausländische Polizeidienststellen weitergibt, man google "Proton, FBI"

That article is being misinterpreted. Proton didn't hand information to the FBI. Swiss authorities processed a legal request tied to a serious criminal case, and only optional payment info was disclosed, no emails, messages, or account content. This actually proves how little data we hold. For maximum anonymity, we accept cash and crypto.

Ottimo servizio

Ho iniziato con la mail free e ora sono passato a Mail Plus. Servizio finora impeccabile. Perfetta anche la gestione del dominio personalizzato. Numerosi servizi disponibili. Molto soddisfatto.

Your algorithm is absolutely terrible

Your algorithm is absolutely terrible. I am getting really tired of being signed out, blocked and then forced to change the password. We have a family account and use the services on different profiles and devices. Your system makes the family accounts useless. Very often my family don't even know they have been signed out. I have complained about this before and got back the poor response it is to protect the account. Our usecase is for personal use only, we use strong passwords and need access to each others accounts. So please fix your awful algorithm?

I purchased the Proton Workspace to test for my company

I purchased the Proton Workspace to review for my company. I paid the full amount for the premium product. After 6 hours of testing, it was obvious it would not meet our needs. Tried to cancel on their website and there was no way to do so. When I emailed to cancel I got the same instructions, that did not work.
Four days of constant emails to them, I hear nothing but crickets. I quit receiving emails and responses after the first day. They will take your order but won't refund if you cancel on the same day you paid. They supposedly have a 30 day refund policy. I guess it could take 30 days. But I will just have my CC company reverse the charges it they refuse to respond.
Beware!

Trovo la piattaforma Proton davvero…

Trovo la piattaforma Proton davvero eccezionale, e mi meraviglio di un punteggio così basso, davvero.
E meno male che i servizi gratuiti sono di alta classe compresa la VPN, che fa quel che deve fare anche se gratuita. I commenti che ho letto mi appaiono un po' troppo nevrotici, eh :)
Grazie Proton, ciao racazzi.

Een aanrader

De negatieve reviews hier op trustpilot hebben blijkbaar niet begrepen wat proton inhoud en slaan de plank in hun review volledig mis. Proton heeft geen reclame en in plaats daarvan vragen ze geld voor de onderdelen. Daarnaast heb je voor pakweg 100 euro per jaar al hun services waarbij je een wachtwoordkluis hebt en een cloud(drive)omgeving. Wat mij betreft een hele faire prijs. Je krijgt hier namelijk heel erg veel mogelijkheden om je online privacy te beschermen, zoals het checken van inkomende mail, het aanmaken van aliassen, het beheren van wachtwoorden door middel van een wachtwoordkluis, etc. Daarnaast zijn er ook nog geavanceerdere tools die je online kunnen beschermen.

Een aanrader.

I am quite SHOCKED that I have to pay just to get 'sent from ProtonMail' removed from my emails. A little bit CRAZY if you ask me.

The proton marketing and pop up…

The proton marketing and pop up promotions are confusing and mis leading. They offered me an upgrade to an annual plan and then a better service without explaining that I had to cancel my exsisting plan. It is obvious that if you upgrade with a service, that you do not carry on paying the old subscption. Very mis leading!
I did not receive any renewal email notices in advance.

Réfléchissez bien avant de vous engager !

Après avoir lu beaucoup d’articles élogieux sur Proton Mail dans la presse spécialisée, j’ai décidé de souscrire à l'abonnement "Proton Unlimited" car il intégrait entre autres, l’agent I.A. "Lumo".

Je pensais donc pouvoir utiliser cette "intelligence artificielle" sans être limité, contrairement à la version gratuite ; pour en avoir confirmation, j’ai posé la question à "Lumo" qui m’a affirmé qu’avec mon abonnement "Proton Unlimited", je pourrai bénéficier des mêmes possibilités qu’avec l'abonnement "Lumo Plus" seul.

Au bout de quelques jours seulement d'utilisation modérée, "Lumo" s’est bloqué et a affiché un message, indiquant que la limite hebdomadaire de chat était atteinte (...), comme sur la version "Free" ; j’ai donc contacté par mail le service client Proton et 48 heures plus tard (...), ils m’ont expliqué que cette limite d'utilisation était "normale" et que pour disposer de toutes les fonctionnalités, il fallait prendre l'abonnement "Lumo Plus" en supplément de "Proton Unlimited" (...) ! D'après eux, les informations données par "Lumo" sur son propre fonctionnement, ne seraient pas fiables et ce, pour des raisons "techniques" (...).

Juste pour information : J’ai posé à l’agent i.a. gratuit "Duck A.I." (GPT-5 mini, par "DuckDuckGo"), les mêmes questions concernant les capacités du "Lumo" intégré à l'abonnement "Proton Unlimited" et il semblerait que je ne sois pas le seul à avoir cru que ce "Lumo" disposait de performances équivalentes à celles de "Lumo Plus" ; d'après les commentaires étudiés par "Duck A.I." dans toute l’Europe, beaucoup d’autres clients semblent avoir été induits en erreur, par des allégation commerciales à la limite de la tromperie (mais pas pour autant frauduleuses, semble-t-il).

Outre la perte financière (j’avais pris l'abonnement pour un an), je suis profondément déçu en constatant que leur image de "professionnalisme", "fiabilité", "sécurité" et par dessus tout de "probité", ne reflète peut-être pas la réalité.

Le délai de réponse habituel du service client me semble excessivement long, notamment en cas d’urgence (blocage, piratage, etc...) et je commence moi aussi, à douter des compétences techniques de certains de mes (très courtois) interlocuteurs mais également, de leurs réelles possibilités d’action ; je comprends mieux maintenant, la frustration ou la colère de certains utilisateurs, abandonnés à leur triste sort et sans aucun espoir d’une solution .

Tout n’est pas pour autant négatif chez Proton et il deviendra peut-être un jour, un acteur majeur du marché mais pour le moment, son système semble manquer de "maturité" et il est donc "urgent d'attendre", avant de souscrire un abonnement ; cette société est sans doute dépassée par la croissance de son activité et l’infrastructure de serveurs a sûrement du mal à suivre.

Je regrette amèrement de ne pas avoir lu plus tôt, les commentaires clients sur Trustpilot ou d’autres plateformes similaires ; ainsi, j'aurais pu éviter de "jeter à la poubelle", une somme aussi considérable !

Ce que je trouve le plus scandaleux, ce sont tous ces grands magazines informatiques qui encensent Proton dans leurs tests comparatifs et lui attibuent souvent, des notes supérieures à 8/10 ! Comment peuvent-ils faire cela, alors qu'il est de notoriété publique qu’un client sur deux est très mécontent du service fourni ?!?

Hi, sorry to hear about your experience.

To clarify, Proton Unlimited includes access to Lumo, but it does not provide unlimited usage. Lumo Plus is a separate add-on with higher usage limits and additional capabilities. We understand how this may not have been clear, and we’re working to improve how these differences are communicated.

Regarding the response you received from Lumo, AI-generated answers can sometimes be inaccurate, and we’re continuously improving reliability to avoid situations like this.

As for support response times, delays can occasionally happen during periods of high demand, but we’re actively working to improve this as well.

If you’d like, please reach out again via https://proton.me/support/contact
and we’ll do our best to review your case further. We appreciate your feedback, as it helps us improve both our products and communication.

Disgraceful: Ignoring a Financial and Suicide Crisis for Two Weeks.

SECOND EDIT:
It has been three weeks since Proton Mail took unagreed upon funds from my account and are yet to return my money and will still not communicate with me.

EDIT:
Take seven days to reply to an email to customer servies, followed by another seven days and no response to my follow up email, but three hours later from a bad review, Proton Mail replied on here.
​I am writing this in absolute despair and disgust. Proton Mail is a company that hides behind small print while ignoring a customer in a severe mental health and financial crisis. I have told this company repeatedly that I am at the point of suicide due to my financial situation, and they have shown zero humanity.
​I contacted them via email well in advance to state that I no longer wanted my account and requested its deletion. They were unhelpful and ignored me. I tried to use the app to stop the renewal because I am in huge financial difficulty, but the system would not allow it. Then, at 5 PM on a Friday, the moment I finally had a small amount of money in my account, Proton Mail swept in and took the very last of it.
​I have been pleading for a refund for two weeks. It took them seven days to offer me "two months free"—an insulting response to a man telling them he is in a life-or-death crisis. It has now been another seven days with no further response.
​It is an absolute disgrace that a company would steal money from someone who has explicitly stated they do not want to renew and then ignore them for two weeks while they are at suicide. This is not just a matter of terms and conditions; this is about a company's total lack of ethics and responsibility toward a person in a desperate emergency. Proton Mail is an absolute disgrace and a disgusting company.

ProtonMail never get back to people…

ProtonMail never get back to you or there is a massive delay in responding, especially if you don't pay for it. When they do respond and you point out it isn't helpful, they get funny with you as if you're at fault. Lastly mailbox size is nightmare but I get it, you have to pay to increase it.

Slecht en duur systeem

Je wordt bij het installeren knettergek van alle pogingen om je een betaald account te verkopen. Alleen met een duur abonnement kun je mail ophalen in outlook, en dan alleen nog de classic! Dit is absoluut geen zinvolle vervanging van de google mail!

Nutze Proton nun seit 5 Jahren am Anfang die kostenlose Version inzwischen nutze ich die Premium Funktion.
Hatte bis jetzt nie Probleme, die Filter funzen gut, Mail Verschlüsselung ist am Start, nicht wie bei anderen Anbietern. Es gibt eine App fürn Desktop und fürs Handy, beide funktionieren sauber.
