McDonald's Kempton Park I want my money.

The bad service I got at McDonald's Kempton Park just for a jalapeño sauce was not a good experience. McDonald's Kempton I want my money for that jalapeño sauce because I paid for it separately and I was told that it is out of stock, I asked for my money back but the lady who was helping me with my order asked me "manje uthi Mina ngenzeni?" then she went to the kitchen and came back with a small cup with jalapeño sauce, I refused to take it and asked for my money back but she just ignored me and continued with other customers. I separately ordered the jalapeño sauce so I want my money for that jalapeño sauce.
