Angry customer

Good day

I'm not happy with the service I got this morning from one of your cashiers named Samkelisiwe Hadebe. she have me so much attitude, she first didn't greet me, I was the one who greeted not even sure if she responded. 2ndly I used my debit card to make a payment which I always use at supersave every month, I told her to choose savings account because it is a credit card that is linked to my savings. He select a cheque account, and it declined. I told her for the second time to select savings account. she responded with a straight face that the her machine doesn't want to go through to the savings account and there is nothing she can do.

I requested her to call her manager for help she refused and kept on telling me that there is nothing she can do to help me. we ended up arguing and I told her not to argue with me, she went on and on. luckily the transaction ended up going through. I want that cashiers to write an apology to me on email or atleast give me a curtesy call before I take this matter up because I know my rights as a customer
