Got a voicemail from this number.  Male with Indian accent named "officer John Brown".  Got another a week earlier from same person asking me to call back 866-978-6981.

 Got my IRS call from an Indian sounding male, gave name of Robin Brown. He informed me that he was calling about the lawsuit filed against me by the IRS and if I didn't call back immediately  the"situation would unfold on me". He never used my name, just"you" and the phone number he gave to call is 202 864 1250. Got 4 calls in two days.

I got the same as most of you. I was told there was a lawsuit by the IRS (never said my name, foreign accent). I was told the name to call back: A John Brown 202.864.1218. This person called  my cell. The call seemed "odd" and I will not call back.

same thing happened to me this morning. called back but blocked my number. number answered but no one spoke...

5/21/14-Recieved numerous recorded calls to contact IRS regarding lawsuit being brought against me.  The call back number was 202-864-1218.  The call stated if you do not return call, you are responsible for what is to follow......or something to that effect.  Of course I did not return the call because if the IRS was going to sue me this IS NOT how they would contact me.  Additionally, there would be multiple contacts between a party & the IRS before a lawsuit by the IRS is filed!
Please people do not fall for this scam.  These people are trying to steal your identity by obtaining personal information.

Yep, I got the voice message also today (5/21/2014).  "John Smith" (with an Indian accent!?) called "from the IRS."  Said the IRS was suing me and the issue is "prime sensitive."  If I didn't call back "the situation falls on you."  Too funny.  Pure scam.

Ignore them.  Total scam.  Operating out of India.

Hi I received a call from this number also saying I have an IRS lawsuit.  I returned call to let them know they had the wrong number.  The man was rude and told me they don't make mistakes and I would be sorry when the cops came to my door.

I received a recorded call this morning claiming there was an IRS lawsuit against me and was instructed to call 202-864-1218.  When I did a person by the name of "Max Campbell" with an India accent answered and claimed to be from IRS started asking for my name.  When I asked him to verify that he is was from the IRS he told me to look up his number and callback.  Then he hung up.

message to call back regarding a lawsuit against me by someone ( I couldn't understand the name).  Foreign accent - Asian i think. Called twice, identical message.  Never said my name.
