Manager a disgrace at Mc Donald's

Worst service ever... So I decided to take my kids to McDonald's Lower Durban road after having a positive report card, only to get treated like a low life.. I ordered on the digital drive thru speaker(all good) then arrive at the pay point and no one is there to take my card or accept my payment. The car infront of me moved on and I proceeded to the collection window. I admitted I never paid and wanted to pay, Now I am told I need to go back around and stand in que then basically start over.

I called the manager of the shift on the 22 June 2022 at approximately 15h00, and explained my situation, He refused to let me pay at the collection window. I then asked for his details and handed him 1of MY BUSSINES CARDS to write it on the back , he refused and TORE UP MY BUSSINES CARD that I paid for and threw it out the window. I was humiliated infront of my kids at left without food..

I had the food in the car in my childs and told by manager I have to give it back its not mine, I could've left without paying, however I am not this person and wanted to do what's right only to get this response.
