Never Trust Uber They ***** Peoples Money Off Their Bank Cards!!!!!

on the 15th of June while I was at work I had an amount of R299 deducted off from credit card, ofwhich my credit card is not registered on my uber profile on the uber app . I want the full amount of R299 which was *******ly deducted from my account to be fully refunded back. I cannot find ubers telephone details and I was not email the details of the trip that I so called took, there is no receipt which indicates so from uber. I would like to know how did they manage to *******ly deduct money from my credit card and I have not used their pathetic rides since the 10th of June of which I had cancelled the trio and never used it. can some one from ******** uber give me a call on ********** 180 to talk about their ******** activities.
