UBER ****! getting charged for a **** second stop from Lanseria airport

This Thursday I requested a trip from Lanseria to Centurion. Midway, we miss the turn, and I ask the driver, and he says we're going to Menyln, like how, because I did not request Menyln Mall. Anyway, we changed the location to the right now. At this point we less than 5km from the right turn. The charge moves from R244 to R385. Annoyed, but I am like, okay, because maybe I am the one who made the mistake, so i thought ( having looked at hello peter, I saw someone reporting the same issue, this is possibily and uber or driver ****). However, when the trip ends, the charge is not R768, with R150 tip to the driver. I quickly messaged UBER and it has been one impossible task. one computer-generated message after the other. and the number given doesnt work. I have been a loyal uber customer. but i am going to take my changes with bolt.
