Bad Service

On the 3rd March i paid a wrong beneficiary via eft I assertained that that the account i paid to had been closed. I submitted a recall form on the same day. was told it would take 7 working days to sort out .it is now 11days and all i get from Nedbank is that they are waiting for the other bank(Access Bank)to respond This seems to be a simply problem. Why could Nedbank call Access bank and find out why it is taking so long
