I had a similar experience Gravy. Had a salesmen insult me via text and management ignore me, ended up having to go to corporate. Missed the first case managers call by a minute, then the guy just ghosted. Wouldn't respond to calls, voicemails, or emails. After 3 weeks of countless attempts, and being given a run around by the main hotline, I eventually said I'm not hanging up until I speak with a higher up as this is ridiculous. I got a new case rep but he has more or less been useless. Very polite, but with no results that means jack shit. He initially told my wife that they can't do a buyback despite what the mainline rep suggested on the first phone call. Then the following phonecall I spoke with him and he said he was starting the process to file the claim for the buyback. Which was confusing but whatever, lets get this going. I asked how long it usually takes to reach a verdict and he said 2 weeks, but would call back 12 or 13 days just shy of that to inform me the claim was denied. When I asked why, he said something along the lines of "Well we looked at the NY lemon laws and because it's past 18k miles its no longer covered." to which I said I would call him back, looked up the NY lemon laws on the Attorney Generals website and for me because the car was purchased used at 32k miles I was covered for 90 days / 4k miles whichever comes first. I would then call back and tell him this and read it back to him word for word, and he paused to think for a second and stated "oh we don't do buybacks on used cars". At this point I'm dumbfounded and I'm like "you knew it was used from the start, so what was the whole point of this redundant process??"
I never had to go to corporate before, and I'm sure every company has its bullshit. But after this nightmare, that is still happening, I would never own another Genesis or any other related brands and will personally advocate against them to friends and family to hopefully spare them the potential nightmare. It's also quite amusing to see older threads on this forum with and see a screenshot email from the rep that ignored me back in the beginning.
