Nonsense service

I just visited maponya mall Mac Donald and I claim 5000 pts for a chicken fold over .The screen kept saying that the offer had already been redeemed, there was no one there to assist by the machines and by the time I finally got help I was told “my bad the timer has run up and you have lost the points” this is rather disgusting as it was not my fault and had there been someone to assist customers maybe I would not have had to experience all this nonsense.I left and didn’t continue to even bother with my order.What nonsense service
