Reading all the reviews I decided to add my story here. I chose EE for the cheap prices and I must say they were the cheapest on the market at that time (2017) - so big plus for that. However, recently they changed my tariff to a lot more expensive. They sent me a letter dated July 2018 informing me that my tariff changed in June 2018. They switched me to a more expensive tariff and it was more than a month before i was informed. The also started changing my DD, first i was on £28 a month soon this doubled to £46 with no reasoning behind it. I emailed them and waited two (yes 2 whole months!) before i received a reply. At this point the credit on my account (the money they owed me) grew to £100. I have raised a complaint, but they have done nothing. I will be leaving them this week but worry that i will never recover the money they owe me. The only solution now is to raise a complaint with Ofgem - and i advise anybody that had a bad experience to do the same. Iresa - the supplier that went bust because of the poor customer service should be a warning for all those dodgy companies. If you cant get it right go bust!!
