Complaint Review: SCI*Stamps.com GrantResearch Emusic.com

I'm a victim of credit card fraud. Got VISA bill with online charges that I never made. Cancelled card a.s.a.p. but e-music continued to bill! When I called them they gave me the e-mail address of where the music was being sent. So I have the e-mail address of the theif! Now what? Was hoping police or FTC would e-mail suspect and tell her she is suspected of stealing my credit card info. But no, they won't.

Does anyone have phone # for Stamps.com and GrantResearch.com?
VISA said they would call these companies but so far they haven't.
