So I'm in Key West and need to get service done on my 2016 Chevy Silverado. I've called their business three times and every time been transferred to somebody's voicemail. I need to speak to somebody alive person. So the 4th time I called back I picked a different department and spoke to that person. They told me if I did not buy the car from them they cannot do service for me. What great customer service.
