Reimbur*****t of voucher and cold food

I was at Glengarry Simply Asia on the 29th December 2019, I had a card with R242.90 and came on a lunch date. At the end the person wanted to pay, I told the waiter not to claim my voucher and she acknowledged my request then the manager comes and the waiter does not tell the person who rang up the transaction that they should not claim the R242.90 and they end up claiming my voucher. I wanted this reversed as I was building up my points to use at another occasion and I expressed my issue but they did not assist in anyway, also my 514 came and it was so cold, I asked the waiter to get me a, new fresh one and not just warm the cold one as it's not the same, they warm my cold one in a wok then brought it back to me. I only saw it was the same one as there was chillies that threw in, I then insisted on a fresh one and they wanted to charge me when the waiter said first time around she will have a fresh one made. Only the 3 time did they have a fresh one made. I had a bad experience and left a real sour taste in my mouth that I could not evens eat the food when it came.
