It's a serious post. I have a USA based customer who is not paying the invoice which is now a year overdue. Have his telephone, emails but now, he doesn't reply at all. His company has a good brandname, and are strongly active on social media (even currently). I nor my company is from US. So what methods can I use to recover money? Can I contact any agencies?
He had purchased some goods from us here and payment was to be made later. He used to reply back earlier but now there are no replies.
