I received a call, from an elderly women, claimed she worked with National Online Pages and that I had an invoice there which was from 6 months ago which needed to be paid. I asked her for the company name again, I explained I never signed up for their advertising, they must be mistaken. She claims I spoke with their rep 6 months ago, and when I cut her off and said I absolutely did not speak with your rep or sign up. She mumbled, we have a record, and then she hung up on me.
I think if I would have been a busier business it may have not been caught right away, so BE CAREFUL!!!
