Boucher Buick GMC of Waukesha

8am brought my 2019 Yukon XL in to service Transmission both differentials and transfer case, oil change tire rotation and multi point inspection Was told it would take 2-3 hours. 11:39 Texted their system to see if car was done-recieved no response 12:18pm called service dept told they are working on it and they will contact me when done 2:23pm called service dept again and was told the guy was working on 2 cars at the same time and he will have mine finished in 30 minutes They would send someone to pick me up at 3pm I live 10 minutes away 3:30 I'm in service dept one other customer was being helped by the rep that was handling my car. The other 2 service reps were at their desks, never bothered to say anything to me for a while or even offer to help me until I finally got eye contact with the rep named Jason. I said I was there to pick up my Yukon and he turned to my rep who was still helping another client. She told him my paperwork was in the basket. He grabbed it and walked me to the counter to pay. He gave no explanation of what was done or breakdown of the charges as is customary when picking up a car. When the clerk told me the amount of almost $1000, I decided I wanted an explanation or understanding from the service dept. So I walked back to service dept but my rep was not at her desk, so I addressed the rep at the next desk, Jason. I asked if there was any reason he did not go over the paperwork with me. He said didn't my rep do that. I said no. I said I was told it would take 2-3 hours and that was 7 1/2 hours ago. the only communication I had was they are working on it and He is working on 2 cars at the same time. Jason replied she will be back shortly. I waited a few minutes and became impatient, so I went back to the cashier's desk and paid the bill. I walked back to the service dept to see if my rep had returned. She had not but Jason had his back to me and was talking to the other rep. He said with an attitude "It's not my problem Don't F*cking complain to me" Jason then turned around and saw me. I said "I heard that. I am never coming back here again. I am done with Boucher GMC!" and left. It should be noted that Jason has been there several years and my interactions are never pleasant with him. He is annoyed half the time whenever asked questions. In fact about 4 years ago when I had my engine replaced (under warranty) I had a disagreement with Jason. When I picked up the Yukon he was going over the paperwork. The paperwork had stated it was a rebuilt engine. They had my car for many months stating they were trying to locate a new engine which was difficult (covid times) They entire time they always stated new engine. Not once did they mention a rebuilt engine. So when I stated that to him Jason point blank told me a rebuilt engine is a new engine. We argued and he was insistent and arrogant. I may be a woman but I am not ignorant,. Calling a rebuilt engine new is like calling a refurbished appliance new or remodeled home new. It simply isn't true. It is "like new" but it is not new. I cannot believe Jason continues to hold a job in customer service. We will not be returning to any of the Boucher car dealerships. I had continued to give them a chance but I am done. I hope this helps others avoid the aggravation I have experienced
