McDonals Atterbury Pretoria Poor Service & No refund

I visited the Atterbury store this morning and ordered breakfast via the terminal. I could not pay at the terminals and was asked to pay at the till point which I did. I then noticed that the one beverage ordered was not a milk shake but a coffee shake for which I requested an exchange. The assistant informed me that she will get her manager to attend to the exchange. We were then asked to wait at the table for service sine I ordered a sit-in service. After waiting for a while. I decided to go to the counter to sort out the return & also query why the food was taking so long to arrive. The supervisor informed me that they will not be able to refund the coffee shake since I had ordered & paid at the terminal, which was not correct since I was asked to pay at the counter. I then told her that I wanted a full refund since I cannot wait for so long for my meals and was going to go elsewhere. She informed me that they do not do refunds. The counter assistant also then informed me that the food was now ready, but it was packed as take-away even though I ordered sit-in. A manager came to attend to the matter and requested that I provide my bank card details. I provided my banking details, but he insisted on me providing my ID number as well which I thought was strange because that information is not necessary to process a return. Also, my card details were on the payment slip. He refused to give me a refund and I left. I therefore request that you refund my money and investigate the managers stance on wanting all my personal information for a simple reversal of payment. I believe that he had ulterior motives to use my details for *****ulent purposes. I will be posting this on all social media platforms to warn customers of this gross violation of a customer’s rights as per the CPA and POPI Act.
