Called @ 3:36 in the afternoon but left no message. Said DC, USA on the caller ID. Don't know anybody in DC. Isn't that where the people responsible for the federal DO NOT CALL list reside? Maybe that's who was calling?
202-770-2429-- Left no voicemail.. Based on what I am reading above either claiming to be IRS or Tax Relief. Either way a scam as the IRS would not call you they would send mail correspondence.
