We moved from Economy Energy at the end of October 2018 due to them raising the amount for next year by at least £600. At the beginning of December I contacted them. They stated that I owed them £140, which I paid immediately and then told me that THEY owed me £133.70. Today, I have contacted them again and they claim it is now with the finance dept. and I will receive a rebate shortly!!! If I had been waiting for the money to pay for Christmas presents etc., I would have been in trouble. They were quick to bank my money - it would be nice to receive theirs!
