Clear Car Rentals — Overchaging

I had prebooked cab travel from ooty to mysore with clear car rentals (ccr) booking id ow1vw1774058 dated 18/02/2022.
Travel date 24/04/2022. Confirmed price rs 3231 out of which 969 was paid in advance online.
On 23/04/2022 at around 8:30 pm ccr provided me driver and cab details for ride on 24/04
driver called me to say that iwill have to pay rs 3700/- in cash over and above 969 advance paid by me. Else the ride will be cancelled. He even declined to accept the fact that advance has been paid.
All means of convincing him were fruitile.
Tried to contact ccr but did not get any support or response.
Ultimately as i had no choice as getting other agency on board at last minute in unknown area was not possible, i gave in and agreed to pay 3700 in cash.
A different driver with diff cab came and completed the trip. Paid him 3700 in cash at the end of ride.
I landed paying 4669 for the ride against agreed price of 3231.
I requested ccr to investigate the matter which went of deaf ears.
In fact ccr representative santosh defended the hike and refused to entertain my claim refund of extra amount charged
