Uber India — Driver collected cash and my uber account shows to pay online again

Address:

No.4,, Agasthiar Street, Pallikaranai

I took Uber auto from Medavakkam to Pallikaranai on 17th Dec 2022. Though the fare indicated initially on my phone was Rs. 77, the driver insisted to pay Rs. 100 and I paid the amount. My Uber account shows that I will have to pay Rs. 77 online. I am surprised how this happens without the knowledge of the driver.
