They just called me. I called that number back and told Allen that if he wasn't careful the US government was going to hit his building with a Hellfire missile. Told him I knew he was a fraud.
Do not waste your time reporting this call to anyone in authority. you can be assured no action will be taken.
I have crank called them back, by first pressing *67 and then their number.
After a few unpleasantries, I spoke in the scammers native language and found they are based in Gujurat. This is an ongoing scam scheme and believe me, they are making money, as he told me. !!
I have received the same B.S. call from 202-681-6828, a person called claimed his name is Officer Brian Allen from IRS in Washington D.C. claimed it was a warrant filed against me and my physical address and left a fake case # to call and inquire about this case number. The best response to this kind of scam calls are to investigate the suspicious activity. I appreciate the other people who shared their experience of this BS calls from a bunch of crooks. This is why I am sharing with others.
