No service

McDonald's does not take care of their customers. I am very disappointed. I wanted to buy a double quarter pounder, only the burger. I went on the app, I saw I could get a aluminum cup if I upside the meal. I asked the drive thru what the min cost would be to get the cup. The deals don't have prices. When I read my code from app it showed aluminum cup on the screen where it displays the order. I did not receive my cup and demanded a refund. I requested to see manager 3 times. I had to make a scene before manager attended. Manager promised to get me a cup from another branch. No refund as requested. Manager phoned me to inform me that Oxford Street had one. Gave me manager name. I went all the way to Oxford Street for a cup. Manager did not have my cup, said she kept it for yesterday only. What now... I went from Gonubie to b/bay and back. Gonubie to oxford Street and back without my cup. I asked for simple refund but nobody listened. I'm not leaving this.. tired of companies **** service or Complete lack thereof. R34 extra for cup that's not available and all my diesel.. Really bad service. ,
