Horrible service, not caring about it's customers, rude managerial responses, no direct customer care line, empty promises etc.

On the 9th of August 2025 at about 09H12am, I purchased a breakfast meal at McDonald's Middelburg mall. On the collection window, the coffee was brought first and on the exchange of hands, the hot coffee over tipped spilling on me and the vehicle. I tried to keep calm while I was feeling the burn, she said "sorry" and continue to offer my meal. I then asked her to call the manager on shift. On arrival the manager (Rebecca) set her apologies, admitting to the note of the incident. She then offered me a rag(cloth) to wipe my self and the vehicle, saying she will look into this matter and deal with it appropriately. She asked me if the coffee was given to me on the cup holder or not? I answered (no cup holder and properly closed). She added that "she was suppose to have put it on the cup holder" but now there is nothing more she can do to reverse what happened. Another lady came by to address me that she will be the one handling this matter, where I detailed that medical attention is needed and my outfit is messed up by coffee stain. I have driven from Standerton to Middelburg for an event but now I have to carry the medical costs and change the outfit or cut my day short(cancel). I logged in a complaint on the McDonald page, then a reference no: INC-C4072-D0B03C was sent to me. On Monday the 11th of August 2025 I tried to make follow ups but could not get through, I continued calling the number *** where later the receiver was very rude answering my call and hung up. On Wednesday the 13 of August 2025 I called the McDonald's Middelburg Mall for the feedback on the matter, the person that answered said "sorry there is nothing we can do" and just hung up the phone. I then called the *** number again and received the response this time and it was professional. I furnished the lady about the incident, she took my details and said customer care will be calling me back. Today I tried calling the *** number and my call was not picked up. I am truly disappointed McDonald's.
