Uber has no proper way to complain

Uber has no form of complaining, their number does not work and the place to get "Help" is basically a guideline for when the customer is at fault. I ordered food at 20:19 which they accepted and have taken the money out of my account before my package arrived. According to the Tracker the driver is still in the same position after collecting my order and yet no movement or any communication from the driver has progressed. The driver does not respond.
