Bad client service

I would like to voice out my unsatisfaction about the service I received from Thulile Ngcobo from your Watercrest branch. On Sunday 26/06/22 afternoon she was my cashier. She refused to use my ID number in place of my rewards card which I had forgotten, by the way I've done this before. Let's say it's no longer allowed,which is not a problem, the manner in which she spoke to me and her facial expression was of annoyance. She never gave me other options, but only saw on the till,the option to use the app. When i asked about it,she rolled hers and told me if I have the app I can get my card details from it. I then asked her why she didn't give Mr options,but she just stared at me. Thulile went out of her way to make my shopping experience unpleasant, she must be taught customer etiquette.
