Uber India — An Uber Auto driver did not return my money

I booked an Uber Auto for my parents from Kharegaon, Kalwa to Bhiwandi on 04 July 2022 at 10.50 AM.
The driver picked up them and dropped them at the desired drop location. The total bill amount for this journey was 282 INR. My father gave him 500 INR and asked for a return. Driver was not having change that time so he asked them to wait and went in a nearby shop to bring change. He took his auto along with him so my parents stayed there, waiting for him. Even after half an hour, he did not return with their cash. So my father went opposite side where that auto driver went to bring change. But he was not there. He simply ran away with our cash. Thus my father called me and asked to contact the driver. But Uber don't provide any direct contact number of driver. They only provide company number which only connects you to driver untill your journy starts. As soon as you end the journey we are not able to contact them. Thus I contacted a support center on Uber App and put my complaint about the incident. Their support person replied me in an hour saying it was our duty to give them/driver correct amount of bill. And they added 150 credit in my account saying we can't add cash more than 150.
The support person was not at all guilty about returning only 150 INR instead of 218 INR. Neither they were feeling that driver's behavior was unethical here. If he did not get any change then he would have asked us to bring exchange. We would have tried somewhere to bring exchange. Running away with our cash only implies that he had something unethical in his mind. I explain this to the support team again and again but they were happy to provide 150 INR credits on my account.
I need a full refund of 218INR to me from Uber along with penalty fees paid for such an unethical experience as well as strict action against the driver.
