As far as contacting authorities, that wouldn't go over too well:
"Hey! He's supposed install an illegal (in most countries) modchip in my PS2! And he didn't! Do something!" 
It's the holidays, and most modders are probably busy. Premods.com most likely have some contact info on the site; check there. If not, I believe you could PM him/her on the forums.
EDIT: Apparently they've been having e-mail troubles, so if you've already tried e-mailing them, they say try again. Sales@PreMods.com
