UberEats has the worst service delivery

I bought food using UberEats and the delivery never came. I got a cancelation message for my order from UberEats after 2 hours of placing the order and UberEats did not bother giving me a reason as to why they were cancelling. I called UberEats and they did not answer my calls. I am nolonger going to be using the UberEats App.
