Uber charging me but no service.

So I needed to use Uber on 21 Dec 2022 morning. Used the app and they deducted R36 of my account. Driver cancelled. Yet money not refunded. Ordered second time, deducted another R36. Driver arrived. Used Uber again in the evening and they deducted R36 from my account. When driver arrived, the licence plate did not match. Refused to enter the vehicle. Driver refused to leave. Cancelled the ride. Money not refunded. Ordered again immediately after and was charged again R36. It was the same driver, but profile and licence plate had to changed to correct details. Refused to go as this is a major safety risk. So I paid R36 three times for a service that I did not use. This is not the first time. You have contact centre to call. No online chat. No email address. And your help support on the app does not have the options that I need for my complaint. Uber is absolutely useless. Bolt has a much better app and service.
