Money out of account - but still no food

Sunday morning I ordered and paid for 2 meals with my credit card at the McDonalds in PE close to Summerstrand. The slip showed that the payment was approved and declined - all on one slip. The cashier asked if I could confirm via my banking app whether the payment went through. At this point the manager, Nosi, had also joined us. I logged into the app and showed the -R140 in my account. However, as credit accounts do, it was still showing uncleared. I tried to explain that it WILL show uncleared as it is not business hours and it is likely different banks, but reassured her that it has indeed gone off on my end and I can't get the money back. She refused to give me the food. She was actually not very helpful at all and kept leaving while I was trying to sort this out. I had to continually ask the cashier to call the manager. She said she'll only give me the food once I can prove that it was paid. I asked if i can come back a few hours later and collect the food - she agreed. I then asked that she write some kind of letter to explain that I did not receive the food. She started writing and my friend started taking a video as evidence we did not recieve food. SHE WAS NOT HAPPY WITH THIS , tore up the letter and refused to help on the matter any further. My friend ended up paying for the same meals AGAIN.

Now I am still R140 poorer, I don't have the food and I don't live in PE to go and ask for the food that I must somehow convince them I paid but didn't get. Can McDonalds please pay back my money??
