Money transfered into the wrong account

I went to Nedbank The Glen on sunday. I had many accounts to link. The bank teller linked the correct account no but under the wrong bank. The bank that was used was STD but the account no belongs to ABSA . I then made a payment of R20k into this account- however the ABSA division has not received the payment . I have phoned the Nedbank customer care line and nobody seems to know what should be done. Kindly assist in reversing and allocating this payment correctly. <br>
