I've lost money two times, both times it was because of my health problems + scam/ fraud or very unprofessional behaviour from 3rd party services that I dealt with.
It's heartbreaking for me.
What to do with them? Force them to repair the damage. I don't really believe in punishments, if it's possible to repair the damage (and at least in one of my cases it's possible) it should be enough. I don't how longer I'll manage to live, but this money could be used by my family... And we really need money, I won't go into details but if I would go public with what we've been through we would be featured in TV
