Some foreigner left a message claiming he was calling about a police matter or something and I'd better call him back before the police came or some such nonsense. Total crap.
If you didn't receive a notice in the mail consider it a scam. The Treasury dept doesn't call you unless they send you a letter first, it would either be a notice of garnishment or a request for you to contact them. They don't need your consent to take your money and they don't really care if it puts you in a bind.
got a message that a warrant was issued for my arrest. I called back and it was a noisy room and I told he to knock this crap off and stop scamming people. she did not know what to say
