Natlist Directory Publishing Seattle Medical Directory, Scam Vendor Bogus Publishing Seattle, Washington

Natlist has been calling my company in regards to some outstanding late fees from 2005 and 2006.  I asked the caller Sylvia what the payment terms on the invoice are.  She refused to answer the question.  She wanted to know how and when I was going to pay the $147.30 in late fees.  When she first called she stated she was with Seattle Medical Directory.  My company did pay two invoice's one in 05 and another in 06.  Both invoice's got paid at 30 days.  After doing more research I found out that she is with Natlist Directory Publishing which my company has identified as a Scam Vendor.  When Sylvia first called she left me a voice mail.  My caller ID had the phone number of 780-472-6397 out of Edmonton Alberta Canada.  Natlist publishes these so called directory's out of every state.  The company has a rating of F on the BBB web site.
