Complaint Review: Executive Business Listing

We received an "invoice" from this company in the mail.  A red flag went up immediately as I had never heard of this company and we have not set our advertising in place.  They are claiming that we owe them $549.99!  I called the phone number and was sent to an answering machine with the electronic voice like you would have at home.  I then did an internet search of the company and found other fraud claims against them.  Don't fall into this scam!!!  Don't send them any money!!!
