These guys are right. The more I think about this, the more it pisses me off. This fucking guy is a business owner first of all, it's bad enough that he would treat his customers in such a way, and then on top of that has the gall to threaten you over a bad review? No way, fuck that, game on bitch. The moment he threatened legal action should be the moment you escalate it further and ruin this cock sucker's reputation. His pussy little letter needs to backfire right in his stupid fucking face. Social media, local news, whatever it takes....spread the word to ensure he gets his comeuppance.
