Uber and ****

I travelled to Durban about three weeks ago. I wanted to use uber there and uber wasn't working properly. I was only able to choose a ride with cash payment, and I completed the trip and paid in cash. I then deleted the uber app and restored it and it started working. But he wanted to charge my card again for the trip I paid in cash. Because their driver had canceled the cash transaction. This is officially a ****. I made the payment from the card and then sent an e-mail to uber support. They refunded the money, but this time they blocked my account. I emailed Uber support again and they wrote me a reply saying that your account has been flagged for inappropriate use and there is nothing we can do. What nonsense is this. I've used Uber in different countries since it first came out. Their own drivers want to commit ***** and they make me pay for it. Be very careful, they may **** you and then call you a ****mer.
