poor customer and billing service

I purchased a family treat meal at chris hani mall drive through. Immediately I noticed sloppy service by cashier. He had me punch pin twice, 1st account he put my card aside instead of giving it back at a hidden view and carried on attending others over line, I didnt let it bother me and on second account gave me slip and retained my bank card. In this time I believe he had a chance to return the card in next window where we had waited for food for about 5 minutes. I realised after several several km I dont have my card and drove back to KFC. I told cashier to give back my card and not to do it again. I asked him to call his manager (Ndumelo), I heard cashier speak with him several times 1st to collect card however manager would not reveal himself. Cashier called for him twice as i waited. I was annoyed at his behaviour, I drove off to use main door to request for him. He admitted to have been listening in as I addressed cashier, yet he did not care to attend to us. I was concerned about the safety of my card. He did not even try to assure me of safety or proper apology. Card ****s are rife towards december and I did not trust the cashiers service.
