Frustration when trying to pay Absa Credit Card

I had a credit card with Absa a while ago and went through some financial difficulty which lead to the account being handed over. I am in a position to pay this off now but I am being given the run-around. I called the Absa legal contact centre and they initially could not find me on the system. I then called the 3rd party and they advised me that I was not on their system either. I called the Absa legal contact centre back and they eventually found me on their system and advised me to go to the branch to make the payment. When I got to the branch, they said I need to have cash because they cannot swipe my card after the contact centre agent told me I just need to swipe my card. I then went to draw out cash, went back to the long queue in the Absa Clearwater mall branch and when the teller punched in my details, he advised me that the account is closed and there is nothing I can do. He then called a colleague over and they both had a bit of a chuckle saying the account is closed and probably written off so I should take my money and go. This morning I called the Absa contact centre back to ask for a confirmation that the account is closed/written off and the contact centre agent told me that the account is not closed. I have no idea what to do now and quite frankly, I am annoyed with the back and forth from Absa when all I want to do it pay of old debt. I can easily take the advise of the Absa bank tellers as well because this is very frustrating!
