Called, said they were calling from Office of Investigation from DC. No additional info would be provided, i.e. physical street address, and complete name of business. Use a lot of legal terms. Apparently I am being prosecuted TODAY. Just talk over you with legal words but would not provide any information in writing, because as they say, they mailed something certified back in 2008 and it was returned.....LOL Not falling for this again EVER!!! This has scam written all over it.
