Received a call from someone claiming he is "Officer Greg Martin" from the IRS. English is his second language, and his grammar was not accurate during the message he left. Basically he claims that there is a "deficiency" (not "discrepancy") in my Income tax and I am to contact his department, the IRS number (not "department) of Criminal Investigations immediately. Apparently there are "serious allegations" of which I need to call them about, and I am to give them all of my Tax info to do this...
