Jim Lupient Buick GMC

this dealership is unable to repair a radio problem. They have replaced the radio in my car and the radio has the same and new issues present. Apparently, they do not check the work that they complete to see if what they did solves the problem but rather calls the customer to just say that the repair is done and that my car is ready for pickup. This is hands down the worst dealership I have ever dealt with. I have been in many many times and have even caught the service manager Brandon in a outright lie! He states that he has never spoken with a member of the General Motors team that had opened up a case number with me. I received a call from GM stating that my radio had no codes and that they spoke to Brandon and he told them this and that there was nothing wrong with this radio! They simply would not know that information had Brandon not spoken to them. This is a very dishonest section of the dealership and one that should not be in place. Simply put, Brandon cannot be trusted and he is the service manager! I can only imagine how many more lies he has told to countless customers to cover other lies. I hat liars and cant stand people that do this to try and better themselves. Honesty is always the very best policy. Further, I had an appt. with Brandon and came in at the agreed upon time to see him personally at his request so he could hear my radio AGAIN after hearing it countless times before. When I arrived, I was greeted by a car runner and I told him I had an appointment with Brandon. Brandon was standing in clear view through the window at the service desk speaking to another service advisor. The young man went in and told him that I was here to see him and words were exchanged with the car runner guy and Brandon at which time the car runner returned and told me that Brandon was in a meeting when he was clearly at the service desk! The young man was clearly embarrassed and didn't know what to say. I said that Brandon was standing right there and I know he saw me come in for our appointment. I then realized that the young man was not at fault and I apologized to him for Brandon not doing his job! I waited and waited and finally Brandon talked to another service advisor who came out and said that Brandon asked him to come out and listen to the radio. This is a guy that was aware of my problem from past countless visits to the dealership. He got in the car and I vented to him after he again heard my radio issue. I told him I was sorry that he had to do Brandon's job and that I was very upset that he lied to me again! We had an appointment!! Brandon told me that he wanted to hear the radio personally AGAIN! The guy that came out, told me that it gets trying around the dealership sometimes and he hinted that he gets put into situations from time to time by Brandon!!!!! I apologized to him stating that I was not upset with him but just Brandon who is the service manager and acting the way he does. We had an appointment and he should have honored the appointment and talked to his service advisor at another time! This dealership is in dire need of a restructuring of personal as the ones they have lie to cover their mistakes. When a customer can catch them in a lie more than one time, as I did, that is pretty bad. I think high ranking management from General Motors should take a deep look at the Lupient Dealership with a fine tooth comb. This is not good for business and the general public. I am and have told countless people about my experience, a gross negative one at that, so that they may not go their for their next car buying experience. This is not a go to the store for a loaf of bread or gallon of milk kind of buying, it is the second biggest item you will ever buy next to your home! How can a dealership treat customers this way. Also, the General Manager, John Aretz has been in meetings with myself, Brandon and that assistant Manager twice so he is totally aware of the issues. The issue w
