I also received this call, and almost fell for it because I am a graduate student who has applied for Federal grants. If you were a victim of this fraud, please go to ic3.gov and report it. Even if they did not actually scam you or get your money, please report it so they will be stopped!!!
I received a phone call from this number this morning. The caller left a message stating the IRS was going to file a lawsuit against me, and I needed to call their number to obtain additional information. I won't be calling them anytime soon. I blocked the number on my phone, so I know they will call me back from a different number because it seems they have an endless pool of useless numbers to use.
I just got the same call. Didn't know the number so I let it go to the answering machine. Really, the IRS called to say they were filing a lawsuit against me. I filed a complaint to www.ic3.gov
