Disgusting service

I stood in an extremely long drive thru queue at McDonald’s Wilropark in roodepoort which is understandable as most people are using the drive thru due to the pandemic at hand. I used my app for a deal on the quarter pounder meal at R45.00. They took so long trying to sort something they had messed up after I had scanned my cellphone. They eventually tried charging me R69.00. I then cancelled the order and asked for a Big Mac. The cashier then said she has too many orders before mine. I am really put off by the service and brand. I’d much rather go anywhere else but McDonald’s.
