Kiran Motors — unethical practice

Address:

Vadodara, Gujarat, 390022

I have a maruti s-cross car and place it for body work with your dealer “kiran motors limited” at channi - vadodara,
Now at the dealer point mr. Tushar (Manager) and mr. Nilesh amin told me that i have to pay the bill amount to kiran motors by cash or by credit card just because, as i’m having insurance from future general and is not covered in cash less policy (As per the kiran motor policy). So i agreed with them and insure that i will pay the bill amount and claim with my insurance.
Yesterday i got the call from mr. Nilesh amin for to inform me that the work is done and car is ready for pick up, so, today i went there to pick up my car but i found puncture in back side tyre of my car and some work has not been done and got surprise to hear from mr. Nilesh that this part is not covered by your insurance!!
One’s i had been agreed to pay him then why he has not done the work?
To claim and redeem the insure amount is my part and he has nothing to do with it.
He should inform me that the work is not completely done as i ask before giving conformation for
Pick up.
The point is, i had an accident by the person who is having own workshop, because of his mistake he agreed to pay me the difference amount which will not cover by my insurance.
This person is in touch with the manager mr. Tushar of kiran motors and as well as with mr. Nilesh.
I just have to inform you that my service and the quality of work get compromised due to them relationship.
Next time i have to think twice to put my car in service at your dealer point and also to buy my next car from maruti or not?
