Honda fit radio problems

Worst ever experience encountered. My car is 10 months old. The radio was faulty. It’s been sitting at the dealership for the past 6 days without feedback. I tried calling the service advisor but the calls just don’t go through to her. I walked in twice , waited for an hour each time only to be told 2 different problems and they refused to give me an eta. They also refused to give me a courtesy car. Will never ever buy another car from the Cmh group and certainly won’t be servicing with them as well.
