"Changed supplier from EE, got a final bill on electricity asking me to pay £11.36.
They chased for this payment, I asked where the gas final bill was. "oh that's in credit"of £54. 18.
Would I like to pay the £11.36 and wait for my refund of £54.18?
Then I suggested just refund the difference...
... One month later, please let me know when I can expect... We are putting your account into review to ensure the bills are correct... I call BS. They are trying to play hard ball and to punish for wanting a refund in time for Christmas when was due this from September."
