Our food was delivered late and cold. They issued a $16 refund, BUT later pulled (without asking) an additional $5 tip from the refund they gave me for a driver tip. The driver had already received their tip at the time of order. They then charged me a random $8.52 service fee without any explanation. I tried to use the app, but they kept cutting/pasting the same message that we aren't eligible for a refund. I wasn't asking for one!...I just wanted to know why the service fee, and the tip being pulled from my account. Customer service sucks!!! That was our first and last time using Uber.
