Grubhub complaint: Failure to deliver my order

Placed an order from China Wok for over. $100. We were waiting for delivery when the driver called. Wanted to get directions because what he had was wrong. We finally figured out that he had our order plus another order. He stated that he would bring the order in about an hour. I told him cold food is not acceptable. All he could seem to say was it was not his fault. Said he would call Grub Hub and I told him the order had better be hot and right or I would contact the bank about getting my money back. So, the grub hub site shows the food delivered about 30 minutes ago. In the meantime, our large food order is missing. This order was to feed me and my 3 grandchildren. My wife had knee replacement and the mother of my grandchildren is there with her. I used your service because I am disabled and can’t drive. Can you fix this problem TONIGHT?
