Ola Cabs / Ani Technologies — Postpaid Bill Charged Even After Paying Cash to the Driver

Regarding the postpaid bill charged to me by Ola for last two rides, even though I had paid the fare in cash to the driver at the end of the ride. This is not the first time this has happened, and I have already sent several emails to Ola support team regarding the same issue. I choose gpay option for payment and was not able to pay online before the ride ended and therefore paid to the driver by cash. Now they are harassing with calling again and again.
