Get a collection agency involved if the outstanding bill is really high, but if you can forgo the payment, tell your friend and friend's of friend privately about the misbehaving company, then just forget about them. You can make more money working with a new company than you would by worrying about this one. It's unfortunate, but that will teach you for the future (like it has to probably every single person who tried freelance consulting before). btw, would appreciate a private message with the name of the Co as well, for future ref ;)
