Terrible service from management and staff

So to start off my new year I decided to visit my local McDonalds at the mall@reds in centurion. At 00:30 I arrive at the drive through and place my order. Besides from the service I received from the lady, my order was wrong and along with her service but food was terrible and I had no nuggets. The lady told me they were out of soft drinks which is ok, it happens, but then she told me I must pay extra for a drink or pay the same meal price for no drink. I don’t understand how it should’ve become my problem to start off with so I asked to speak with the manager. His name is Isiah. Isiah came to the window and said he is sorry that there is no soft drinks. He did not ask me how he could make a plan or what else he can get me. Eventually I found out I can receive a shake which I then said is fine. Driving through and checking my order I realized my nuggets were missing. I went back through the drive through where other people were placing their order and receiving wrong orders. I asked to speak to the manager and told him I did not receive my nuggets. He asked if I even ordered nuggets. And I told him I did and still specified which sauce I wanted but that wasn’t added. He then said “Well are you going to pay for it”. Disgusted by the service and just wanted to get back home I told him obviously I’ll pay for it. In my opinion because of their mistake I felt I should’ve been compensated. Anyway, so I end up waiting for my nuggets for 20 mins?????? While everyone is receiving their food before me. It’s nuggets?? How does it take 20 minutes and watched as the nuggets for being served to other people before me. By the time I got home my food was cold and we all know how cold Mcdonalds chips taste. Disgusted to say the least and safe to say I will not be visiting ANY Mcdonalds soon.
