FNB card division help desk unhelpful

I have been transferring money from my ABSA bank account to FNB credit card via EFT for the past 10 or more years. On my last two payments the money hasn't been reflected on my FNB statement as been received. Went into FNB branch in Newton Park where they were very helpful and helped to log a call to trace my payment. A week later I had an email reply to say the money has been receipted against my FNB credit card I then did another transfer this past weekend and have the same problem. Went back to FNB newton park and the lady was very helpful once again and phoned FNB card division and dealt with a very arrogant male who wasn't willing to help. Said the wrong account is been used by ABSA when the EFT is done and ABSA must just reverse the payment ..nothing he can do and wasn't even willing to try. How come the last person could sort it out and why is it happening all of a sudden. I will wait to see how long it takes for this money to go through and will then close this FNB credit card and move to ABSA .. Can't stand it when it is a persons job to help and they have this attitude, they should find another job. This is very frustrating to say the least.
