Oh I misread that as "I threated to sue if I didn't hear back in a week". Oops, sorry, my bad.
As for trying it myself, I guess it's simply because whenever I get into such a situation, I lose my nerve, butterflies invade my stomach, and I can't think straight. Just calling Visa to try to report it gave me the same kind of jitters, I really hate it.
I will, however, report the information I have in my possession to my local police department. That way perhaps I'll lead them to something, if I'm lucky. Nervous or not, I can try to do my part.
