Beware of the scammers!
Sadly I can see that my story is identical to all other reviews left for this "company".
After discovering a combi-boiler rusty pipe leak, I did several attempts to find a plumber and this company (rssloodgieter.nl) replied quickly that they can help and on the same day, consultation price being around 42 euros. An hour later a young male was at our door, and after checking the leakage he told me that the price would be around 428 euros (including one hour labor cost) but could be slightly higher if he had to spend more time working. I found this a bit excessive, but due the emergency of the situation we agreed.
Fifteen minutes later he declared (after cutting all the pipes) that he needs to go "shopping" for more parts and disappeared for about half an hour, only to finish the job 25 minutes after his return.
He claimed that he spend 1h30 at the job ("shopping" time included) and asked for 1187,43 euros for the final bill, charging extra 275 euros for "disassembly" and other ridiculous charges and declared that TVA was not included in the initial price:
189927 Voorrijkosten € 42,35 x 1 € 42,35
189923 Start Tarief + Diagnose € 295,20 x 1 € 295,20
189916 Meerwerk tijd per 10 Minuten € 46,10 x 8 € 368,80
189908 Denontage raparatie € 275,00 x 1 € 275,00
189908 Btw € 206,08 x 1 € 206,08
Totaal incl. BTW: € 1187,43
At that point I decided not to argue and sort my complain with the company, however when I called their number, the same person (I am mostly sure about it) pretended to be the office receptionist although I could hear him driving and told me that as I agreed on the price, they will not refund me.
I am currently considering a legal action against them, if anybody is interested to take a collective action feel free to contact me on Telegram @slawrydoe
