Sumo レビュー 

The young lady was pleasant & efficient & a pleasure to talk to.

I signed up based on the pricing and feed in tariff listed on their website plans.
Once I signed up the contract they send had higher prices and a limit on the size of inverter you can have to get a solar feed in tariff, this is NOT listed on their website.
Unless you read the fine print on the contract they send you, you will be getting ripped off.
An absolute disgrace!

Dear Sumo Energy Customer Service Team,

I am writing to express my deep dissatisfaction with Sumo’s current policies regarding rate adjustments for existing customers, which I encountered firsthand during a recent experience with your customer service.

It is extremely frustrating and disappointing to learn that when Sumo lowers rates for existing customers, customers are required to call and confirm the change to benefit from the reduced rate. If a customer does not call, the rate remains unchanged. This is not only inconvenient but also illogical. Conversely, when Sumo decides to raise rates, these increases are implemented automatically, without requiring any approval or input from the customer. This inconsistency in policy reveals a lack of customer focus and fairness.

When I called to discuss this issue with a Sumo representative, I was informed that “this is the policy.” However, simply stating that it is a policy does not justify its sensibility. This approach comes across as a tactic to keep customers on higher rates unless they proactively inquire, rather than transparently applying the best rates. This is far from being customer-centric; rather, it feels as though Sumo prioritizes company profit over customer satisfaction and transparency.

Additionally, I have realized that my current rate is significantly higher than Sumo’s standard rate, and I am uncertain how long I have been charged at this higher rate. This lack of transparency and customer focus has left me completely disappointed in Sumo’s practices and approach to customer service.

I hope that Sumo takes this feedback seriously and reevaluates its policy. A truly customer-focused company should automatically apply lower rates to existing customers, just as it does with rate increases. Failing to do so only creates frustration, distrust, and the impression that Sumo is not committed to fair customer service.

Thank you for addressing this complaint, and I look forward to your response on how Sumo will ensure fairer treatment of existing customers moving forward.

DO NOT SIGN UP FOR GAS - Delays in transfer and Sumo will not give customer any timeframe on the transfer

Joined Sumo at the end of july 28/07/2025, Sumo customer service told me i would get transferred after my last bill with my current provider.Recieved my bill from my current provider start of September 01/09/2025 ,after a few days still wasn't transfered ,so i gave them a call.Sumo customer service advised me they need to organise a meter read, meter read was done on 13/09/2025.

As of 19/09/2024 still not transferred.Call sumo a couple time, customer service advised they can't do much about gas transfer takes time,just wait.Customer rep name Chelsea was even very rude, "feel free to sign up with a different retailer"Absolute joke, avoid at all cost

Helpful and efficient call centre staff and calls are answered quickly. Usage prices are competitive.

My call taker answered my questions clearly and concisely and explained exactly what I wanted to know.

I recently had the pleasure of speaking with a representative from Sumo and I must say, the experience exceeded all expectations. From the moment the call began, the customer service was outstanding. The representative was not only courteous and professional but also incredibly knowledgeable and efficient. They took the time to listen to my concerns, provided clear explanations, and resolved my issue promptly.

What stood out the most was their genuine willingness to assist and ensure that all my questions were answered. The level of patience and attention to detail was impressive and truly made me feel valued as a customer.

It's clear that Sumo prioritizes customer satisfaction and invests in training their staff to deliver top-notch service. I am very pleased with the support I received and would highly recommend them to anyone looking for reliable and customer-focused service.

Kudos to the team for a job well done!

My query was dealt with quickly and the lady had a good attitude and polite manner.

So bad.. 2 times since signing up a couple months ago I have sat on hold over an hour trying to figure out the texts iv been sent saying there conflicting my address or something and will cancel my power? Its very confusing I am not sure what is happening all I done was connect my electricity and constantly getting messages off them saying this then having to sit on hold to get no where? Just saying it’s something on their end no apology either I have all the texts an phone call screen shots

Very professional and knowledgeable person most capably answered my queries and steered me to better more economical plans for both power and gas. Thank you Breanna.

Jasper was a PHENOMENAL customer service representative, I sincerely wish I get to talk to him again should I need any help. Potentially the best customer service experience I've ever had. Kind, patient, and attentive with our needs. Wonderful person.
