Complaint Review: Business DataUSA

This internet company will call you unsolicited in the middle of the day.  They will only record a part of your conversation so that when they play it back, it sounds as though you have agreed to a service when in reality, they state that you already have an account and owe them money.  Then, when you call to complain about the invoice, they call you back three times--their number is blocked on caller id.  They play the partial recording and try to insist that you pay the bill.  Meanwhile, when you go to their site, it looks like a 12 year old created it.  There are no links, no samples of other "listed" companies, nothing.  They are such a HUGE scam.  They will yell at you on the phone and threaten you, but if you don't give up and threaten back, they will "delete" the account.  It is unbelievable that small businesses, who are already at their wits end with this economy, have to deal with such finanacial predators.
