McDonald’s complaint: No sweet and sour sauce received

At 22.28 on 3122021 I ordered 1 x 20piece nuggets, chilli cheese burger meal and a chilli cheese burger. The order was placed via drive thru and we were one of the last few cars to be served before closing.
When leaving the drive thru I did ask if the sauce was in packet and the lady ed same. When arrived at home, my son advises that no sauce was in the packet. The following day I went to Mcdonalds at Chatsworth centre I explained to the cashier of what transpired she then referred me to Wiseman who mentioned he is the store manager. he said he cannot help me because they are a different company which was a laugh to me and he said I need to go to Central Durban if I required the sauce. ( what a joke ). I then asked him if i can purchase the sweet and sauce sauce, which I eventually did and it roughly took the staff at Chatsworth to handover 4 x sauces 10 minutes. my son eventually enjoyed his day old nuggets. Receipt attached.
