Cars24 Services — Service bill reimbursement

I have bought the ciaz car from Cars24, which has so many mechanical issue which was not declared to me by Cars24 during selling the car.
When I took car to service center for service then I came to know major abnormalities in car which coster me Rs32k/-
When I asked cars24 to reimbursement the amount as car which they have sold had major abnormalities then warranty person ( Mr. Bijender Singh) denying for reimbursement of the bill.
Now when I rectified the issues than they are saying that we will send the person for problem verification but agreeing on reimbursement.
Plz look into the same & support me to get the reimbursement
