UBER SA Disappointment!

Good Day, So this past Saturday I downloaded the Uber SA App to use their services, I was a bit nervous Uber'ing alone as a female but I completed two trips which were short distances and both driver's were very pleasant. I was so happy to be part of the Uber community. But then my experience turned into a extremely unpleasant one! Two days later I'm having lunch, then suddenly my phone went crazy with non-stop bank notifications one after the other. These were multiple large amounts being debited off of my account with the reference "UBER SA Help.co" which were the exact same references from my actual trips, I phoned my bank immediately to stop my card then to find out someone cloned my card and Uber was subtracting money out of my account! I tried contacting UBER but there are just no telephone numbers to be found, you have to send a dispute via the App, which was just ignored and not attended to! I am extremely disappointed with UBER and I will never be using their services again, it was not exactly the best first experience one could have! I will advice all my friends and family not to use their services, as my bank mentioned that this happens quite often! I am now in a position where I cannot utilize my own money which I worked hard for because a company has poor security. I am just an everyday good citizen put in a postition where I have to fill in a lot of forms and make phone calls and go into my bank to explain why I need my own money back because of a lack of security. I am praying that this gets sorted out! It is unacceptable!
