Poor service

I am utterly disgusted with the poor service of the Kia dealership. It has been over a month since i had my car taken in for a service and each and every time it is mentioned to me that there is another add-on issue with the car. It has gotten to the point where my calls were avoided and not returned. The receptionist, Faye, has dealt with my wife on numerous occasions and she too, has since avoided calls from my wife and i. I spoke to the service manager, Garth, and he told me the car is up and running and just needs the air con done and we would receive the car the next day. The next day came and when my wife called again, he had said there is an issue with the warranty and that he has also had enough with dealing with us. Well, i am in sales and with that being said, i would never treat a customer with that amount of disrespect. It has gotten to the point where i would love to take legal action against this so called good company they claim to be. Once again, there is a level of disrespect, a lack of communication and a serious level of negligence coming from Faye and Garth, in particular.
