I leave a one star because I can't leave a zero star. GrubHub canceled an order when they could not fulfill a delivery. When I reordered through another restaurant and they could not fulfill that one in a timely fashion, I went to cancel the order and they told me that I could not do that because I've had too many cancellations and concessions. How the hell do I have too many cancellations and concessions when they are the ones that canceled the first order? I didn't request the cancellation I wanted the order. They just couldn't deliver it. If I were starving, and GrubHub were the only place I could get food, and they were willing to give it to me for free, they could keep the food. I used to be a frequent customer several years back and decided to give them a chance again, and this is how they treated me. Almost 5 hours and I still didn't get the ice cream that was ordered.
