Got a flat tire on Friday night. Fortunately, my new car purchase came with a few nice perks. Someone came to change out the tire and put the spare on for free, which was much appreciated since I was also sick. The dealer also gave me one year of tire coverage, including a new tire change for free. I didn't really want to go there for this since it's a bit far, but you have to go there for the tire coverage.
Called the dealer's service center on Saturday morning to make an appointment.
Service lady:
Ooh, I don't think we have any open slots today. Let me put you hold for a second.I get transferred to someone's voicemail and then try to call back and am sent to her voicemail. Left a message, called back a few hours later, and every time it went straight to voicemail. Great. So I go online and book an appointment for 7:30 AM today. Got an email yesterday confirming.
Go there this morning and give them my name- they have no idea who I am and my name is not on their board with the list of reservations. So much for that. I go to see the same lady I called and ask about the tire coverage and she goes
"CHEVY DOES ***NOT*** COVER TIRES. [THE DEALER] IS DOING THIS AS A FAVOR TO YOU." 

Waited 2.5 hours and she comes back over to tell me that they don't have any replacements in stock and to come back tomorrow.
Went out to my car and found it blocked in by another car. Nobody is outside and I can't get back in the way I came out.

I then see the same lady come out and start smoking, then flag her down. She finds whoever it was who parked there and the car is moved. Good times.
Pretty much cements that I won't be using these guys for service. There's another dealer much closer to me and I'll try my luck there when it's time for maintenance.
