Uber over charged me

Yesterday I ordered an Uber and he was clueless as to where to pick me up. When he eventually came late approximately 45 minutes he was extremely abusive. When I confronted him about his rudeness he told me to get out of his car and drove off before I could collect all my belongings. In the process he broke my spectacles. I then proceeded to order another Uber and made an error to put in the wrong address. I informed him when he picked me up and he said that he would correct it for me. When I got my email with the cost I saw that I had been charged R358. 00 instead of the usual cost of about R190.00. I knew that i may have been charged a fee for the destination change but to be charged double is outrageous. Numerous attempts to get an answer from Uber have fallen on deaf ears. I use this service at least twice a week and am going to use another taxi service if this is not resolved. I put my complaint on the app and they responded and closed the query giving me no recourse to respond.
