Scam scam scam. They had a recorded message of us on the phone from 2 years ago! They are claiming we owe them $... good luck scammers, your info is going right to our local attorney generals office. DO NO PAY THEM A PENNY.
ITS A SCAM.

A man (and later a woman) called and said the business I work for placed an online ad in 2009 and never paid the bill.  I am the only person who handles advertising and said "no we did not" and then I politely asked them to " please take us off your calling list." He started yelling at me saying things like, "You people don't pay your bills" and "you're terrible at your job". He called 12 times in a matter of 30min just yelling into the phone, calling me names.  Then a woman called from a similar number and did the same thing. When I asked that they send the "bill" to our address so I could let our attorney handle the matter they said, "We would rather deal with you".  Hmmm, of course they would.  Of course they don't want an attorney involved.  What a scam.  I called the police and they are investigating it.  I would suggest you do the same.  They are trying to intimidate you into giving them your credit card information....DO NOT fall for it!
