Worst bank ever

Nedbank make all these promises on adverti*****ts to change to Nedbank, until your are a client then all assistance stops. My wife made 4 deposits into my go banking and Nedbank credit card on two separate dates from her FNB account. The money was successfully paid into the Nedbank Consumer Card account. These payments were never paid into my credit card accounts because we used the old cards card numbers as reference. I phoned the call centre and they said that we must get the proof of payment and go to the branch. My wife also phoned FNB and they confirmed that the money was successfully transferred. I went into the branch today and now they want my wife's bankstatements to show that this money was not send back into her account. All they have to do is trace the reference number from the account this money was paid into. isn't the proof of payment enough proof. Why must we now go and draw statements just to show that the money was not send back. I really don't have time to to go back and forth and the money is in the Nedbank Cosumer Account. We even gave them the account number where the money was paid into (as confirmed by FNB).
