Ola Cabs / Ani Technologies — Driver cancelled trip and charged high amount

I had booked cab from Dahisar to T2 terminal (Mumbai international airport) on 8th March 2022 at 9:32AM and shared the OTP with your driver. The amount was showing 518/- while booking the cab but after the trip ended he showed me screenshot which showed RS 754/- and when i told him that while booking it was showing 518/- he told me there may be some issue with the app. So please show them the bill and i will get difference amount refunded. When i checked my app the trip was showing cancelled. Hence i understand that your driver committed fraud with me and i want you to take strict action against him and pay me my overcharged amount of Rs 250/-. I have attached all the required proofs to prove the fraud hence expecting strict against such drivers who are cheating passengers in the name of OLA. He must have cheated other passengers too hence i demand strict against him. The car and driver was same. I paid him 500 (cash) + 254 (Gpay) = 754.
