Bad customer care

I paid off my credit card last month on the 15th and I think it reflected on Absa system on the 17th asked for the account to be closed it was done 5days later. Surprisingly in Friday the 2nd I got a message that 500 has been deducted or debited to pay my credit card. I brought that to Absa attention and I was promised a reversal since Friday I have been calling till Sunday and nothing. Ended up having to si the reversal myself with my bank and that is wrong as it affects my score and I am the one charged also. I am disappointed in Absa service and I now know it was a good idea for me to close my accounts with them... Bad service all the way
