With thousands of people getting unsolicited fax calls from this number, why can't the FCC look into the company behind it? I contacting my state attorney general. You should, too.

Several calls mid-March - some with +1 in Caller ID (as if from another country) but identified as CO-USA, so that fits. Sounds of fax-attempt. No fax # here though, and of course it's on the do-not-call list, ha ha....

Repeated faxes.
