I used greenchoice for gas and energy for a year, I regularly updated my meter readings when they asked me to and still paid the same monthly fixed fee of 38€. At the end of my contract, I gave my meter readings the day I left the house. Yet, they sent me an email a day later asking me to resubmit my meter readings, as if a ghost had changed them since. Obviously I could not, and they likely "estimated" my consumption, as written in their mail if no new meter readings were submitted. About a week later, I receive the final bill of 147,81€! A very nice "estimation" from greenchoice. I contacted them through whatsapp, as indicated on their website, to seek explanation about the final bill. I received no response.
