Zoomcar — Accident and payment issue

I registered for amigo program by sept 14 2021. While listing they said the company (Zoom car) will make sure the car is safe by their before and after trip checklist. By Oct 3rd at 6am I got a booking which ended by th 11.30pm. When I check the car morning there was big scratch in bumper and the bumper was not in the position. I called the customer care number and made a complaint regarding the same. When ever I call they promise they will send a technical team to check the damage, till this date I din got any call from Zoom car or none visited to fix the damage. They promised the damages will be fixed immediately. Kept the car in same place for 3rd day without cleaning. Kindly help me to escalate this issue to next level. Thanks in advance.
