Subaru of Gwinnett

I bought a Subaru from Subaru of Gwinnett. Its service department is the worst. I left 2 messages - one of them is to service manager. No one called me back. This was last Friday. Today is 06/10/2021. I called at least 3 times to schedule a 30 thousands miles service. The initial operator, when I pushed for service department, are just terrible as well. One of them just sends me back to the main menu or to an auto voicemail. I had to schedule my car service with other Subaru dealer. I will not forget this very rude treatment from them and I will never do my business with Subaru of Gwinnett. I want to add that a young man who sold me the Subaru was professional.
