Excellent Service
All Service people were nice was greeted right away. Joseph White was very attentive to issue I had and went over and beyond to get it resolved which he did. He kept me informed on what was happening and I left very happy.
Great customer service
The service department was the epitome of customer service.Sherman greeted me at my car to open my door and inquire as to my service needs. The service manager came out to personally greet me to make sure that I was happy with everything. The service was timely. I have purchased several cars in my 63 years and I’ve never experienced such service at this level. My car salesman, Kerry Moses saw me in the service lounge and came out to make sure I was still happy with my purchase. Kudos to Hennessey and the service department!
Very good
Good Job
Awesome experience with service?
I worked with Service Rep Sherman and he was very detailed and helpful. After the initial diagnostic on my vehicle, it was well over 1100 for repair, but Sherman advised it could be fixed same day. I asked if an oil change could also be performed and it was. The repair work was complete in about 6 hours, my vehicle was washed and the total came in around 950.00, even though that was a lot and it less than I expected to pay, so shout to the Hennessy team for taken good care of me that day!
They make keys for buicks older than 15 years. 2 other buick dealerships wouldn't do it. Said it wasn't in there computers or somthing. Definitely go to this dealership over the others.
Service that i received was completed.
Laura was amazing
I always receive excellent customer service at Hennessy Buick GMC. Joseph White is an amazing advisor, my 2010 GMC Terrain is running like a new car. So happy that all the issues with my car could be resolved in a single day.
It was a pleasure doing business with Hennessey. Jovan price and shandia brayboy made my experience wonderful. The whole staff was friendly and made me feel like part of the family. I would definitely deal with them again and will also give them a 10 star referral.
Top Shelf Service
Thank you Mr. Kerry. You we're awesome as always!!
Highly recommend Dee Hines. I was on a tight schedule the day I stopped in. He went out of his way to help accommodate my needs. Dee is a genuine guy. Very professional and easy to do business with. Thank you again for all your help Mr. Hines !
The customer service team is very helpful and very professional and very knowledgeable anytime I need service they start on time.
Although things were chaotic because of the current UAW strike, I was provided great customer service and provide frequent updates on all matters related to my car service.
Good customer service
I had a great experience at Hennessy Buick dealership in Morrow, Georgia. Couldn't find what I wanted to buy in my town so I went to Georgia. Shawn Rivera, my salesman was awesome to work with & he's very professional, treated me with respect & I would recommend him & Hennessy dealership to everyone ... ☺️
Frank went above and beyond to make our experience great!
Demetrius Hines is awesome!!!. He was very informative and the best part, he was not "pushy"! There were issues during the signing, which resulted in not purchasing the vehicle. The next day Demetrius called and offered to bring the corrected paperwork and the vehicle to us, which was 100 miles away. Because of his personality and his willingness to help correct an error, we drove back to the dealership and completed the sale. Demetrius didn't sell us a vehicle, we purchased his customer service!!!!!!!
I had an emergency type event occur with my car. It needed an alternator. I called my service coordinator, Joseph White and told him what was going on. After having it towed to the shop, he stayed and received the car from the tow company. Although he was off the next day, he periodically checked with the mechanic and kept me updated about my car. The cost of the repair was a lot more than expected, but I appreciate him and the mechanic getting my car back to me ahead of time. I appreciate you all! Thanks!
Mr. Joseph White and his team is to be commended they are very knowledgeable; I am very satisfied with the work that was done on my 2015 GMC Terrain.
Mrs.Jackie’s customer service was phenomenal. Thank you ma’am.
