Uber India — Dual charge ? -Paid cash and my Uber account shows amount due!

Address:

No.4,, Agasthiar Street, Pallikaranai

I travelled in Uber auto from Medavakkam to Pallikaranai on 17th Dec 2022 at about 11.45 am. The amount initially shown on my phone was Rs. 77. After reaching home, the driver insisted to pay Rs. 100 showing his mobile that the amount to be paid was Rs. 88. I paid Rs. 100. When I opened my Uber app, it shows that Rs. 77/- is due and to make the payment online. How the driver collected cash when the payment was supposed to be online and how Uber sends notice to pay online after making the payment in cash?
