CAR SERVICE EXPERIENCE WAS BAD

Took my car for service to this center, and they packed my car outside their yard as dirty as it came , but i saw them washing other cars that came for service.,and with every service we get around we do get a car wash... For that i felt like they done nothing on the car .,Customer Service is important in every industry ,We all paying so why treat client/customers differently ? After i reported the matter to their customer service center , no one responded so i Will never take my car there again nor recommend them.
