Maruti Suzuki — Service issue

Dear sir,

My name is Athul.A, I am an Ex - employee in Amararaja batteries(Amaron) and I have worked as Service Advisor for 8 Years in Tata and Mahindra Passenger and commercial Vehicles
.
I have given my official car Alto 800 (KL58K-7476) to Mandovi motors, Hennur, Bnaglore for running repairs to Service Advisor Mr Sreenath.
My complaints

1 Engine oil changing
2 Four wheel brake cleaning
3 RH side ac vent grill changing
4 Water service and to check all the oil levels

The cost estimate price 5000/- and estimated time 5 pm.Mr Sreenath call me at 3.00 pm and updated me the car will be delivered at 5.00 PM, but i got the car at 7.15 PM.When he explained the service details the three unpredictable works

1. AC blower cleaning
2. Ac vent cleaning
3. Throttle cleaning and charged 1160 plus tax for washing and oil level checking

When i asked about the additional works to Mr Sreenath, he had suddenly deducted the charges for AC works and throttle cleaning from 5500 to 3280.All the additional works are Value added services and i know what are benifits and incentive amounts for a service advisor for Value added service.
When i handover the vehicle to mandovi the wheel cups are taged with wiretags.When i got the vehicle wheelcups are not tagged with wiretags .On the way itself i lost my Front LH wheelcup.and brakes are very less(Rs 250 was charged for brake cleaning)


My point is we are not at all satisfied with this service.and who will be responsible for my loss (My Wheelcup and 1160plus tax).


Please resolve my issues ASAP, otherwise i will go for consumer court and Maruti Higher Sessions.

Please find the attached file of the scanned bill copy

Regards
Athul.A
