Really disappointed. Happy with my initial purchas...

Really disappointed. Happy with my initial purchase of my new 2015 Cardinal. Everyone was extremely helpful until after the sale. The service department as of recently calling 3 different service personnel including the service manager with no return phone call. Was the same thing when I first purchased my camper about a year ago. No one would return my call . After 8 phone calls over 4 week period with no response and I also called the finance manager who also never called me back. I had to bug the general manager to finally get service to call me back. It seems like the same old thing , once they make the sale the customer isn't important anymore.
