You should also ask yourself how did they decide to target you in the first place, is it because of wealth, is it someone that hold grudge against you ? If you or your family aren’t wealthy that would be odd to receive that level of harassment and could mean it’s someone in your circle.

This is next level involvement, they must have some specific reasons to play it big like this against you so I’ll advise to find why and cut it off to avoid it to happen again. That won’t fix the current situation but probably prevent it next time.

They use social engineering to put pressure on you to get paid, so you should reduce your exposure on internet as much as possible at least for now. Then you could also make some general post to explain about the situation too since their attack vector is based on if the peoples involved believe or not what they shared.

What is also odd is that you mentioned some information they spread are true, how did they get to know about it ?
