Homan Auto Sales Inc

I bought a vehicle less than a month and a half ago and it's been in the service center five times already. Their solution is to return the vehicle and give us back our money. We don't want to return the vehicle, we just want it fixed. When the sales guy asked me if the next thing they do doesn't fix the vehicle, then what. I said it's up to your service guys, they're the ones who have to figure it out. He laughed. I didn't think it was very funny. Now they refuse to work on our vehicle at all.
