Bad customer service

I recieved very bad service from an Absa Port Elizabeth Central Branch.The consultant that attended to me was Chantel Swarts. She helped me to transfer from a student cheque account to a gold vakue bundle account I was not issued with a card as I already had my old card. When I checked my charges I was charged for a card I never recieved. When I went back to the branch to the same consultant she could not assist because she claims I recieved a card and she deals with a lot of clients and cannot go back to my achieved statements and check the mistake so that it can be corrected and I get a refund. As an Absa client I am very dissapointed.
