Napletons Schaumburg Buick GMC

I arrive at the service department at around 9:30 am, He asks if I had an appointment, I didn't, which was MY mistake. I tell the guy my envoy denali is making a weird grinding/rubing noise in the front passenger side wheel well. Ok, we will diagnose the problem and call you in a few hours. 3:00 rolls around no phone call yet, I know they close at 6, so I decide to call. I give them my name and get told the mechanic is with a customer, and will call back in 2 minutes. An hour goes by, and no phone call. I call again, get put on hold for a while, I eventually get connected to the service department voicemail. I hang up and call again, get put on hold again for a considerable amount of time, and eventually get hung up on. I call again, get put on hold again. I eventually get connected to someone in the service department at about 5:00, just to be told "We never got around to diagnosing your vehicle and we are getting ready to leave, sorry." He says I can leave the car over the weekend (closed on sat and sun) or come back Monday. I tell the guy I'm picking up my car. I'm furious at this point, and decide to call the the sales department and ask for the dealership manager. I talk to the guy that claims to be the manager, tell him my great story, he says no problem, he will take care of it, that's not how they do business and will find out what the problem is. He even says that he will not ignore me and will make sure someone calls back. An hour and a half goes by, and you guessed it, nothing. So I decide to go over there and talk to him face to face. I get there and ask to speak to the "manager", I'm told he is busy, but your car is ready to be picked up. Has anything been fixed, no. While im asking questions the salesperson is getting my keys and calling someone to get my car, so now I'm basically being rushed out. I get my keys and get the sliding window shut in my face. Again I'm in complete disbelief. I decide to get in my car and leave before I end up doing something stupid. I admit to my mistake of not making an appointment, and I went into the situation knowing that my car wont get fixed that day, I just wanted to know what was wrong, so i can plan out transportation for next week. Even if they didn't diagnose, it shouldn't of been such a pain in the ass just to get an answer. Here is a statement from the about us section of the dealer website "Customer Satisfaction still tops the priority list. Whether you visit a Napleton store for sales, service, or parts your experience will be one of the industry's best. "
