I’d call the cops. They’re likely intoxicated.
They may still get them for drinking and driving. I know they do in Canada.
I did end up calling the cops, and when they showed up it sounded to me like the mother was trying to say” I’m gonna own this- I’m the one with insurance blah blah blah.” I’m pretty sure her daughter was driving . Probably uninsured. Probably should have gotten a DUI.
Hope you called the police.
This is like my nightmare when it comes to buying my house
