Very bad experience with service

When I buy this car then sales man response me super but the bad experience I faced when I went for first service after the first service even there did not wash the car properly also there made two marks on the front bumper of the car and even there ride the car around 100kms when the car was in showroom there have not even checked the wiper water level all those the water level is low also there charged me 400 of labor charge in first free service I don't know what kind of service is given to me by kropex dealer (singasandra) it's better to avoid this showroom for service.....
