First, the delivery guy didn't want to come up stairs using the elevator. I had to insist that he come up to my company's doors to deliver my food. (All other delivery guys deliver to our doors.) Then they tried saying I didn't pay for my food. Which I used this app to pay for my food and it was a pending transaction at my bank. Had to have the delivery guy call his boss and sit there for an extra ten minutes arguing with the guy that I paid through Yelp. Food was okay but the customer experience was awful.
