Uber India - Paid cash for noncash trip

Date- **/**/****
Driver Name- Kamal
Driver Mobile Number-(+**)-**********
Driver Location- Belghoria, Kolkata, West Bengal
Description- I chose for non-cash trip. But, after boarding in the car, the driver told me that from his device he has changed the payment method from non-cash to cash. So, I didn't say anything and after completing the trip, I paid the driver by cash. The fare for the trip was INR ***.**. I handed INR *** in cash to driver and he returned me INR ***. So, driver took INR ***. Next day that is **/**/****, when I checked Uber app and found that payment has not yet been settled. So, I called the driver twice on his mobile and then he picked up and said he was busy and would like to talk later. So, next day again I dialed driver and he said he will check and will settle quickly. I waited for * days but the driver didn't call on my number. So, I again dialed him and he said he was busy with his family problem and being a good person I didn't insist him anything about it. Then again * days later when I dialed him, he told me he will go to Uber India office and settle the payment on that day. But nothing happened and again * days later I dialed driver *** times and every time he cuts the phone. Now I feel pity on myself and from now onwards I will not believe any app based cab driver.
