Uber ripping people off

I'm really really annoyed,I requested a trip today from Maponya to Jabulani mall ,this guy accepted the trip and while I was waiting for him to come he started the trip and I thought maybe he is already here and I noticed that he was not getting any closer but rather further and further away at that time I decided to cancel the trip and request another ride to my suprise I was charged a cancellation fee for a ride I was not even in . Please refund my r29.12 .I had to request another ride.How can I make 2 requests a few minutes apart from the same location and yet the trip that did not happen was already at a different location?
