Driver pocketing part of the payment for the trip of R175.00

Good day. I made a trip with Uber from Windsor Park Kraaifontein to rondebosch east on Wednesday 20th November 2024 at 10.11 am. The fare was R 175.00 On arriving at my destination I paid the driver as follows: 1xR100, 3xR20, 1xR10 and 1x R 5.00 coin. The driver write on my account I only paid him R40.00. This is a lie. Uber south Africa contact details and their app to complain is useless. I have been using Uber for almost 3 years What shoddy service My question to the driver while I was waiting at the gate of my destination why dud you not hoot or call out that paid you short? Driver named Lancelot vw polo. I even changed thus trips rating from 5 to 1 actually should be 0 zero
