****** by Uber south africa

Good day I have a complaint about Uber South Africa and I'm not sure where I can take it further as they not seeming to take me serious. I was in Port Elizabeth for the weekend and i decided to take an Uber to the hairdresser instead of using someone car as the amount of the trip came up as 69 rand. I then saw when I got into the car there was an amount of 202 rand that was reserved on my card. As soon as I got out of the car the amount of over 300 rand went off my car. The return trip home was 86 rand and the traffic was much heavier. I am upset and they have refunded 110. The guy asked me where I was from and what I did. When I told then via the messages I sent them that the return was 86rand they don't explain the difference. I'm still being charged 202 rand. I feel this is *********. I'm from Port Elizabeth and never has this happened in Johannesburg. Their first excuse was that the guy never ended the trip but the message went off straight away after I got out of the car. Uber ****** me here and they not willing to explain the difference in same km trip. Please assist Lurisha
