Why is Uber eats so horrible in their service?

I've been waiting for my order for over 2.5 hours at this point. The customer service agent just disconnected the chat mid conversation saying they have to help other people. Lol they didn't even finish helping me.

What kind of 💩 company is this? Also you can't rate restaurants anymore? The quantities are abysmal despite the upcharge.

And God forbid you don't reach out to Uber about an issue within 48 hours cos you know you're busy. It's your fault the restaurant fooked up the order but you were too busy to message Uber about the issue.

Why would I order delivery if I had the time?
