I got the same call. I asked why they are working on Saturday and calling from 209 area code claiming they in Washington CD. I said I would pay the $2400 if they had my social security number. The supervisor was the same guy with the same accent but spoke in a deeper, slower voice. He does have my address, name and cell phone number. I tried finding out just how much information he had on me.
I asked him if he was proud to be a scammer preying on the poor and mentally deficient. I asked him if his mother wanted to abort him at birth. I told him if I find him, I will fry him. He hung up on me.
First I started receiving calls from so called lawyers wanting to help with an IRS suit in the D.C. The man had a heavy India,Pakistan or Nigerian accent. Today I received the robo call from agent stating this is the finial attempt and if I did not call they would proceed with lawsuit. I new that each one of them where fake, if The IRS wanted to get me I would have received a registered letter or a agent would be at my door. One question since they call interstate why doesn't the Feds do something.
