Terrible app/customer service

Was overcharged for ride, got a refund, but when I tried to use the app again to charged me again the overcharged amount. I have since been trying to get the issue resolved but the customer service is built into the app only (no phone number, chat, or email address) and the app keeps cutting off my conversations, not allowing me to respond to messages. Its very aggravating and now I will not use the app again as I fear it will continue to make false charges every time I use it.
