Ola Cabs / Ani Technologies — Charging extra money though I paid full cash to the driver

I have booked OLA Auto's from Dec 29 to Jan 07. The Driver agreed to come only if full cash is paid. I had paid him full Cash after the ride, Even though OLA says it has paid from OLA MONEY

1. I have not subscribed or changed my settings to pay through to OLA MONEY
2. The OLA DRIVER has not informed me that OLA has paid the Money on behalf of me.
3. I have written to OLA Money Customer support but no response
4. I am asked to pay extra Rs.500 though i paid the driver with Cash from OLA Money
5. I am charged extra Rs.50 now for late payment.
6. I am getting continuous annoying calls from OLA as well.
