unsatisfactory banking practice

I accidentally transferred money from my cheque account to Wesbank instead of my savings. I called the bank to help me reverse the transaction, they told me I must call Wesbank. I called Wesbank to reverse , they told I must wait for the money to reflect then I can ask for the reversal. I waited 3 days for money to reflect in my Wesbank account. i called to do the request as i was told, they said i must send a statement as proof of the transaction.....which i did, waited 2 days to follow up and they confirmed that they have received and logged a refund which will take 7 to 14 days .

My problem here is FNB and Wesbank are under one umbrella, why such a hustle for a transaction that they can see and confirm themselves. I have all their authentication process why does it take so long to do that refund but very quick to accept that transfer.

I feel that should be the case when you have transacted between different umbrella not something that they can all pick up but still make wait for ever for money they are still going to chow any way.

PATHETIC!!!
