Left a recorded message on my company phone that I only got part of.  They insinuated they were part of The Department of The Treasury and something about avoiding a grand jury for some reason or another and it was their second attempt to make contact.  It was the first time I ever received a phone call like that one.  I call searched and the phone number at one time belonged to a company called Aardvark Locksmith out of Washington DC.  It probably doesn't belong to them anymore.  I can't find a listing in DC for that company.  So perhaps it went out of business.  I'm guessing it's a creative bill collector or scam artist.
