DD Motors — Complaining about the Car service

I had given my car for car service and i Haven't enough time so i hired a Serviceman from DD motors peeragarhi so he took the car from home and i had given him all the instructions
Related to car service such as Wheel balancing, upholstery cleaning, fip calibration, front disc brake pad. After he gave the car I was not there he gave the car keys to my worker. After that i had not used the car it's on garage because I was ill only my son had used the car for family purpose. After that i checked the car there was no upholstery cleaning done by them and my car had also gear issue and gives a lot pollution I am very disappointed by your poor service please kindly take action immediately.
