Treating customers unfairly Ubereats

So ubereats keeps moving the time of my delivery. The app shows that the driver is making a stop somewhere else first which shows why it's taking long so I cancelled it and it says I have an outstanding amount. He says he took long because i ordered from too far. Which is nonsense because the app already told me hes selfish enough to take 2 orders at the same time and now hes lying. I've been ordering from the same place it has never taken a decade.
