This company called and asked to verify my business address, days I'm open and time.  She claimed she was from YPpages on line.  I know YP pages tries to bill people acting like they are the Yellow Pages to get people to pay bills.  They send an invoice with a similar logo and assume people will pay it.  I used to work for a large corporation and we caught onto their scam.  I don't trust these people as far as I can throw them.
