I call service and parts and no one is answering the phone? Left message no call back and called 5 more times and sat on hold for 30 minutes and still no answer so I call the number again and the sales department answered like always and I tell them I can t get through to parts and they say oh sorry they are supposed to be there but they must be out back or something? I say well should I go to another dealership and was told yes you will probably have better luck? Doesn t make any sense.
