Un Happy Client

I transfer money into a wrong FNB account, when I call Capitec call center the lady by the name of Tshego tells me that they must investigate and it will take 14 days just to do a reversal and the charges are going to be R160, can Capitec explain to me the logic in this. As soon as found out that the account number is incorrect I called my bank to do a reversal now am told that I must wait 14 days on top of that I must pay.
