Medlin Buick GMC

Update: They scammed me into a $3900 service package when I made my purchase, I request refund on 4-17,I still do not see the refund until June.. After 2 weeks waiting, a few calls and even went in person, my refund check is mailed on 6-30, but it is not the full refund, only $3122. Watch out buying vehicle with them. Towed my truck to from Medlin to Deacon Jones. They took my truck in without any problem. They also provided me a brand new SUV as a loaner. I won't make any purchase or use Medlin's service in the future. I won't recommend Medlin to anyone I know. Purchase experience was really pleasant, but service department , especially the manager James Stroud, is not helpful and does not seem to care about customers' needs, only does the minimum, does not follow what are required to be done by dealership under courtesy warranty. The most unpleasant part is he gave me "education", start saying: I am educating you... Took my brand new 2024 GMC sierra 1500 which is purchased from Medlin 6 months ago and only has 5300 miles in on 5th Feb, I was told it needed valve body replacement , this part is on national back order, they do not know when the part will arrive. Medlin said they did not have any loaner available so they sent me to Hertz to get a rental car which is a Malibu. On 8th Feb, I noticed the rental car's AC could not blow out any cold air, so I contacted Medlin service department, I was told to work with Hertz directly. I contacted Hertz, they said they do not have any other vehicles available. So I contacted Medlin service department again see if they could provide me a proper vehicle I can use while my truck is out of service. The manager James Stroud was not willing to help by saying providing a comparable vehicle is not warranty required ,that would also cost $50 more per day, which GM wound not reimburse them. He also "educated" me that I could go to any dealership in the country and it did not to be Medlin, also he did not mind working on my truck at the same time like he is doing me favor. When I returned the rental car back to Medlin on 10th Feb, James Stroud told me he did what could but just not what I asked. I attached the Service Bulletin -GM Courtesy Transportation and Roadside Assistance Program which my truck is under covered for reference, I do not think I received the required services. And Medlin, service department manager James Stroud seems does not care at all.
