Poor customer service

I called German Autohaus to get my car serviced. Spoke to some unfriendly gentleman called Edgar. He was impolite, unfriendly and dismissive. I then decided to go directly to the service house hoping to get better service and got exactly the same service I got over the phone. I walked out and decided to use someone else. I would not recommend them even if it was the cheapest. Their customer service is horrible. I don't know how they still operating given that they have no customer service.
