Uber eats ****s people.

I ordered 3 bucket for one at KFC. I wasn’t able to edit my adress and when I wanted to change it, the app didn’t allow me. I resorted to cancelling the order so I can reorder. Uber eats charged me a penalty fee of R156, my whole meal money. How come?? I want my full refund. Uber eats always provides a bad service.
