Respect sir,
I'm have taken car from sai service
Car details:
Mh48ak7735
Alto vxi optional
Chassis number: 00998291

I had taken extended 2 year's warranty from sai service and recently i had given my car for service in the showroom
The person incharged at show room charged me for ac leakage he told me there is 260 grm gas in cylinder and it must be 400 there was no gas leakage in the car and they charged 1500 rs for it, and they didn't even inform before filling the gas, now they are forcing me and threatening me to first pay 1500 then after take away the car
If this is the way you treat your customer what type of service maruti is giving. Very bad services
And what type of people your hiring who are threatening customer for taking away our own car.
Giving this type of service to comman people who have already given money for extending the warranty and now they are taking extra money on warranty
Please check the details and i'm waiting for your positive reply
For your customer
