Has anyone else had luck with Ubisoft support?

I’ve used their support site and submitted both found bugs and crashes. Instead of acknowledging that the game is at fault, first it was make sure you have all updates, delete and reinstall... (I told them I was on switch and using physical cart, and that support had already had me delete and reinstall the update data for an issue with the season pass not showing as purchased), then they tried to say that the crashing was because my switch was too hot. First I’ve had repeat crashes from cold boot, including from trying to put it in standby with the game running, and when it has crashed mid game, my fan isn’t running at high rpm which would point to it being overheated. (I’ve had that happen but with a different game, and I can repeat it). Now for some reason their trying to say it’s due to “connection” issues or “dns errors”. I can kill my WiFi and play it offline completely, and still have crashes.
Is it just me or do their support techs just lack intelligence?
