I am disappointed at Menlyn McDonalds, I went there to claim my point for a chicken fold over and the gentleman at the till advised I open the App and click on redeem which I did and the points disappeared however they stated that they did not scan the QR code and that I have to wait 30 minutes before it reappears, I had to waste 30 minutes of my time walking around at the mall and the points did not appear again in my balance, the staff did not seem to care much to even check and investigate, they just told me about 30 minutes just to get me out of their faces, I would like my points allocated back to me. This incident took place 15 May 2025, points taken for a chicken foldover I did not receive
