Macdonalds fast food

I placed an order on the online app but realized that my order time was two hours. When I called Macdonalds helpline I was advised that my order had gone to a restaurant that did not deliver to my area, I was then advised that I would get a refund. I advised the lady that I did not want a refund as I hungry, she then said I'd have to pay again in order to get the food delivered. She assured me that the refund would reflect after 7days which would be on 28/05 till today 04/06 I have not received a refund. I even called them today and they wouldn't give me a specific timeline on when I can expect feedback as to why I haven't received my money back. Never mind that I had to pay twice for one order, they do not even bother to make amends for the trouble I had to go through.
