Ola Cabs / Ani Technologies — nightmarish experience with ola cabs

I had to travel from nanakramguda junction, hyderabad to hyderabad airport to catch my flight. My booking experience goes as hereunder:
1) booked a cab vide crn [protected] - 4.49 pm
Waited for 10 mins but driver couldnt reach my place as he wasn't able to follow gps and reach location, hence had to cancel trip
2) booked cab once again vide crn [protected] - 5.07 pm
Waited for 10 mins after booking the cab. Driver reached pickup point but, said that my booking does not reflect in his app hence denied trip. I had no option to cancel the booking for which i was charge rs. 50
3) booked cab against vide crn crn[protected] time 5.23 pm
Waited again 8 mins and the cab reached. While the driver was entering the otp, he also complained that my booking vanished from his app.
Driver accepted to take me to airport with same fare (Which was 2x of normal rate) displayed in the app which was rs.1026/-. As i had already lost 45 minutes in trying to get the cab and futher delay may make me to miss my flight, i had no other option to accept and travel agasint payment of cash.

I had to go through stress and inconvenience because of technical isseus of ola cabs and i had to pay money without getting a bill / receipt.
Even now my above trip is shown as scheduled?? In my app,
I am at loss as i wont be able to reimburse this official trip without bill.
I urge ola to arrange to refund the above trip expense spent by by paying cash to ola driver.
If i am unable to get a proper response, have no other option to go thorugh consumer forum and launch a formal complaint on this poor quality services by ola cabs and harassment faced by customers.
