Refund not paid

I hired a car on 21 May and returned it on 23 May. When I called enquiring about the refund of my deposit, I was told that the payment would be made on 26 May and it would take up to 10 working days for the funds to clear. The funds are still not in my account. When I called earlier I was told the funds were paid to card that does not belong to me. I was told I would be called back after 30min - it has now been more than 5 hours.

So it’s either Avis paid my money using someone else’s card details or they are refusing to pay what’s owed to me. Either this is an awful way to treat your customers.
