Firstly - Are you certain that this claimed, 'rebated £872 premium' payment has not been made direct to the debt management company that is handling your affairs. Have you checked?
If not : -
robo1973 - I have the loan statements and I can't see any rebate listed, only payments I made.
You should respond back to egg in writing; asking them to point out the exact date when they claim to have made this rebate to you, where it was made to and to whom any alleged payment was made.
robo1973 - Is there a good chance they are hoping I'd accept and not question it?
It would not be the first time a financial institution has tried it...... nor the last !!!
