They call you & harass you for your personal information. Claim to be the I.R.S, then call back & say they're the F.B.I

yes, I just got a call from this number claiming that they are the IRS. I think this is fraud but they have too much information about me. they are saying that I didn't pay the service tax which is imposed by the law since 2011. I cannot find any thing online under this name.

I got a call from this number too, all they have is my name (which they didn't say right at all) and home phone number which many other advertising agencies have.

I did get a call from this number stating that they are from the dpt. of treasury investigation division. I called back and what so bizarre the phone system they have so bad.  I could not understand any thing. when I asked what this is all about they hang up and after the second call they said the paper they send out and did not reply to!!! off course I did not receive any thing. The I called again and demanded to speak to supervisor. they hung up!
Can someone shed some light on this. is this a  scam or legit?
thanks

I got a call from this number too. Some Indian guy claiming to be Kevin Peters telling me that he sent some papers to my husband and waiting to hear back from him. Also from dpt. of treasury. Won't give me any info and told me to give him this number. I told them I am going to check and called back. Turned out to be the criminal investigation dept. Kevin Peters picked up the phone. Told them I am not giving this number until I am sure. Then I checked and found this webste
