Just received call from 202-599-9653 claiming that he is calling from IRS office, He said that there is 3 criminal cases file against me form IRS. In reply i said I am nor aware of any thing like this and did not received any letter from IRS about any case. He got little upset and and said that they did send 3 letter on my address and i fail to reply so local sheriff department will issue the warrant to arrest, and he want me to talk to department of investigation head to understand the case in detail, I told him to send me register notice in mail and don't call this number and ask him his name and his agent #, he gave his agent # DC23140-1011 and can't understand his name, he was keep insisting to talk to department of investigation head on 3 way calling and if I don't then he will send local sheriff to arrest me in one hour. I said send them i will be waiting for them and hangup the call
