Disgrace UberX charge Benjamin CY 381879

I got Uber X to pick me up at my house and take me to Brackenfell 5 minutes away. He told me to change the request on my app to a quick stop over I gave him my phone and he did it. When we reach the parts store he said no it never went through but dont worry we can work something out cash. When i got home he asked for R30 cash which i did not have so he said just tip me R30 and we done. When I checked my statement a few going up was more and coming home was more than what was quoted initially. So I ended up with three charges. What a thieving disgrace of a human being . I am going to open up a case against Uber and their driver. I will no longer use their services neither will the Italian students . His name is Benjamin Reg. Lic plate no. CY 381879
