BEWARE! Left a Computer generated voicemail supposedly from US Department of Treasury, "if you do not return the call ..... legal procedures ....IRS...." the voicemail was not clear. This is a scam don't fall for it.
The IRS will always contact you by mail.
Computer generated message supposedly from the Treasury Dept. said if I don't call them back all they can do is "wish me luck". Yep, sounds just like the treasury dept. Total scam.
