Absa useless service

I have a credit card with Absa that has been upgraded to a master card. Both credit cards show on my account list on internet banking. The old credit card account and the new credit card account. I did a transfer from my cheque account into my credit card and by error the old credit card account which shows on my list of accounts a week ago. When realised the credit card account didn't allow me transfer the amount of R4000 that was made. I called absa and they advised to send a mail to *** which I did. Nothing happened. I sat on the phone for more and 2 hours between credit card and cheque account and no one can assist to show where my funds are. This was escalated and nothing yet. So a week later no nor can find my payment although I made an intertransfer and no assistance. Absa is useless and there is no one to assist. I will definately be moving all my savings accounts etc to FNB.
