I finally found the actually company calling and trying to fax people. Thru Paetec Comm and then Windstream Comm and now to company called Level 3 Comm. Their phn nbr is 501-604-1700 www.Level3.com.
I hope this helps people.
more and more of callers like this. Research turns up that if you accept the fax it's a phishing scam. A message or various sorts all the the same goal - TO GET YOUR MONEY! - seems many are from the middle east using automated recording connecting their call with a Canadian phone # so it appears to be a Canadian calling or faxing. Fairly cheap to set those things up, but pays big when they get a victim to give out their bank info, credit card info, etc. knowing what they're game is doesn't lessen the annoyance or irritation, but spreading the word may prevent someone from being duped into giving out personal information and getting scammed.
