Who called from 7206398819

Failed junk fax

This number 720 639 8819 is auto-dialing my "Pay as You Go" Cellular Phone and racking up unwanted  charges for failed FAX calls.

FOUR calls to my fax machine within 10 minute period.

I was on a call when this number came in three times within 6 minutes of time and i don't know anyone in Denver. I got suspicious that it may be a telemarketing.
