I also received phone calls from 203-485-2105 and 203-485-2068 and name ID showed as Capit Greenwich. One lady said to me that there would be a warrant for my arrest and she called my home several times each day and I don't know what she really wanted from me. I called the number back and I heard a Indian guy's message. It looks like it's the same group of people. Thank you for reporting it here so that I know it's a IRS Scam.
I received also a call from this number 203 485 2105 Indian Accent they call several times they have no clue but they try to claim that they are from the Internal Refund the same story... be careful from such SCAM ...
I just revieved a phone call from 203-4852105 and the lady with a heavy accent informed me that I have a warrant for my arrest about my taxations, I advised her that I am aware of their scam and this call will be reported to the FBI, she hung up right the way. The other number that called me was +1 (203) 422-9407 same story only a guy was acting as an agent. SCAM!! Be careful!!!!
I also got a call from a guy with accent claiming to be Sam Hoffman from IRS today. He said there is an outstanding warrant on me. His call back number is 347-305-4235 I believe it is the same guy.
