Trash service and disrespectful cashiers

Am so irritated and angry with the staff at pep east rand mall, it took me a whole 20min to make a simple payment using my ackermans card, whereas I forcefully had to make payment using cash or leaving the items I wanted. They refused to seek help from customer service as to how to use the account card. I ended up calling the stupid ackermans customer service, went through an Indian woman telling me about money transfer, it ended with the call being cut. The staff practically took the items in my position and told me to go at ackermans, coz they don't know why were these establishments joint coz it doesn't make sense. It was not my 1st time making purchase using this card at pep, but because of a teller named Gugulethu and some guy with drad logs..I felt like a fool, imagine if I didn't have cash??? it didn't end there, I eventually took out cash and I still had to wait over 2 min to get change as I purchased with 100 rand and the girl didn't have change in her till, I offered to give her 2 rand so that she can give me 50 rand.. she refused.. and continued to make me wait 4 change. I have been a customer 4 pep and ackermans for long time, but I must say I have never received such trash service.
