Cars24 Services — Delivery person accident my car

Address: Rohini sector 10

I bought a car from cars24 on 10 feb 2021 Renault Kwid which cost me at 209700 which I agreed to pay. They told me there is minor issue in car that the clutch is very hard and need service which cost arround 2500. I agreed to pay that as well after delivery and service. I asked the sales person that I am not that good in driving so I need someone from cars24 will drop to my stepdoor. The sales person agreed and help me droping my car to home. But unfortunate situation that guy accident my vehicle and it costing me 8000 without my mistake. That guy agreed to pay 2500 only rest I need to pay to repair the car. I am not sure if he going to pay for that or not. We took the vehicle to local service centre to repair it and he said he dont have money with me and he will pay me after salary. When I told him its an urgent situation and I need my car fix asap. That is why we took the car to local service centre instead of authorised centre because that gonna take 7 to 10 days. So I called cars24 customer service and they said to speak to same sales person only no help. Next day I contacted other sales person for same situation he said we dont deliver the vehicle . If someone is that is completely his own responsibility not cars24. The other sales person said to sell this car on olx. I need help because the car is insured but transfer is not completed yet. Please suggest what to do.
