I got a new 800 number for my business. I received a "Listing Order Form" to review my company information. I updated my information, signed the form thinking this was the customary FREE service I received previously with my other business number. Today I received a bill from US-Yellow National Yellow Pages for $225.00 with a xerox copy of the form I updated and signed for a free listing. After doing some internet searches, I discovered there were many complaints of this scam from others in regards to this company in Jersey City, New Jersey. Since I was tricked into thinking this was for the legitimate yellow pages and I signed a document for what I thought was the FREE listing, am I obligated to pay this invoice? From the other complaints I have read about this company, many have refused to pay and received threatening phone calls from this company as well as collection agencies. Can this company put a negative mark on my credit?
