Credit Card to be closed off

I phoned the customer care dept for a settlement on my credit and was given the amount, settlement was paid, Phoned the call center and was advised that thy don't close credit card accounts I need to go to the branch, the branch phoned the call center and was advised that thy can't close it because there is an R27 outstanding, I told the lady at the branch, I was given the amount that I needed to settle, why mst i pay extra, apparently the lady at the call center was suppose to advise me of other charges which she didnt, I told the lady that thy should pull the call recording and listen... I need my credit card closed and the paid up letter..
