Sai Service Station — maruti celerio - car spoilt when given for service (20, 000kms paid service)

Address:

Mumbai City, Maharashtra, 400018

After receiving the car after paid service. I identified the problem in the car and reported it.

At first they accepted and tried to resolve it. After 2 attempted they simply said the car is suppose to be like this.
After 3 months of continues follow up, they compared my car with a new one. Where they accepted my car has a problem.

Now, when i am asking them to repair the problem, they are not responsive.

Clearly for no fault of mine i have to suffer through this issue.
