Complaint Review: First Alert PC Inc

This company, First Alert PC Inc keeps calling and faxing our office claiming we ordered "yellowphonepages.com advertising.  We did not.  We have ads posted through AT&T for the real yellow pages and they also keep asking for a person that no longer exists.  The person they ask for has not been with our company for many years and has since re-married, has a new last name and moved to another city working for one of our vendors so I am in touch with her on a daily basis.  I have seen others report this scam and have read where they will claim to have a recording of someone ordering this service but when asked to hear the recording, non exist.  They have been told repeated to stop calling, that I am aware that this is a scam and today we received a fax threating to use an outside collection resourse.  They really need to be stopped.
