Uber complaint: The driver charged me thrice the amount and refused to return.

I was traveling from Dahisar (west) Mumbai today (Friday 13th August, 2021) going to Vasai at 9:40 AM. While booking on the Uber app, the indicative price appeared as Rs 458-570 and would be charged in actuals on completion of the ride.
When I reached my destination, the Uber app. did not show the final amount as the network was down and id not reflect the and I paid the driver Rs 500.
In few minutes, I tried connecting to the UBER app and the invoice amount turned out to be Rs 167.
I called the UBER driver and mentioned that the invoice is reflecting as Rs 167 and since I paid him Rs 500, he should return the amount back; to which the driver, in a rude manner, said that he will not return and that I can take the matter directly with Uber.
This is a case of absolute cheating as when at the end of the ride, when I asked the driver, what the final amount was reflecting; he said he could not access the app since the network was not available.
The snapshot attached in this message has details of the driver’s name and car number.
