Appalling service

Certainly the worst after sales service on any level across all sectors I have ever seen. A brand new car had to be returned twice for all sorts of leaks, the second time for the same leak plus another new leak. Sure, cars break, but the service when repairing a customers broken car, treated me like a delinquent who hasn't bought 3 new cars from you . I had to continually phone to find out *** is up with the car, no correspondence, car kept for 3 days, without a single update. The service manager wipes his ass on messages left. Today I try to book said car for 1st service, booking person demands VIN #, I only have registration on hand, bluntly with rude attitude refuses to assist me without VIN, even though I bought the car from you. Fuming I hung up, my wife phoned back, suddenly no VIN # needed. I am disgusted, you'll get better service from the ****a shop on the corner! I cringe when I know I have to deal with Autohaus after sales care!
