Bad service from Uber

On the 14.06.18 i requested a ride from kemptonplace to Esterpark, The trip was R13(After applying the R25 promo code Granted by Uber.) But i was charged R140, the Driver Thabiso no. Plate :DZ67WM, didnt end the ride after dropping me off and I didnt check as ive always trusted that Uber Drivers do ends rides. It clearly shows that Thabiso transported another client to Tembisa, address :47 Sam Molele drive Tembisa on my account. I reported the matter immediately to Uber but i was not impressed with thier response, they just apologised and made an excuse for Thier driver,stating he forgot to end the trip. if he forgot to end the trip he would have called or texted me to apologies before i even picked it up but to shoe he did it on purpose,he just kept quiet and he still hasnt apologised.and uber only refunded my money back on the 17.06.18 This was such an inconvenience and now im sceptical about requesting with my card,ID rather change my payment method to cash, although i wont enjoy the Cards benefits Seems like the driver took chances as He saw i was using my card to request.
