So have you cashed the refund cheque or not ?

Do keep up. The OP banked the cheque, and it bounced.

Surely they would only bounce the cheque if something had changed on the account since it was issued.

Wouldn't have stopped you getting your mail redirected.

I did do that for a period, just not long enough to catch the cheque. But thanks for the useful input *sarcasm*.

Yes I cashed the cheque I received. It was then revoked and I haven't had another one since.

You mentioned there was a change of supplier after you moved out, is it possible your credit balance was amended after this took place?
If your account was closed to a estimated reading & the new supplier had an actual reading when they took over it could have meant as recalculation of your final bill too.
