Uber India — Extortion of Rs 945 by driver over and above uber fare as Petrol Charge

I took an intercity on 17 Aug 21 from Danapur to Bihar sharif for which I paid Rs1881 as fare. However, driver forced me to pay Rs 945 as petrol charges over and above the fare. I have tried reaching uber customer service full day on 17 Aug through app and twitter, but of no use. Please refund the amount asap.
