To update, my current credit situation is now quite different.
Apparently, the customer service agent who was dealing with my request is no longer an employee.
My credit of £340, included government payouts, so is reduced to £219. Through the delays of repayment, they have manged to further work out an up to date set of accounts that results in my current credit to be £87.41.
I am so confused, and insulted, at the moment, that I really do not know how much this shower actually should refund me.
When offered this final amount, I was asked by the agent, "Is this alright?"
I was impressed by the level of loyalty to Eon that your posts seem to demonstrate. I wonder if the next Energy supplier I move to will have a forum.
