Friendship Chevrolet review: Seller/manager

I traded my car but was not happy with it. Traded on a Friday. Monday called them told them I was unhappy with it that I wanted to get my other car back. They refused said it was to much paperwork would not return my calls after that. I know for a fact that you have so many days to change your mind. It was so unprofessional. All I wanted was to get mine back. I didn't even drive it 10 miles when I called them to tell them I wanted mine back. It's such bull
