Ola Cabs / Ani Technologies — Issue with Ola rides

Hi Team,
Good day!
I wanted to let you know and need clarifications on the below serious issues
CHARGING EXTRA MONEY- I wanted you to let me know whether OLA has approved charging extra money from customers for the cab drivers or not. Because for all rides, drivers are charging extra 30-50Rs. If I deny it, they are demanding it, mentioning that OLA HAS APPROVED to charge extra money.
CHARGING FALSE PENALTY- Additionally, in the worst cases, drivers will accept the ride and will not attend our phone calls. Later the same will be cancelled by the driver and the penalty will be charged from my account and this is happening in most of the cases which is kind of a cheap trick currently handled by OLA.
NO USE OF OLA WALLET- Also, I'm still not sure why OLA has a wallet option as no drivers are accepting this mode and if I choose it, drivers will cancel without even letting us know.

Regards
