This number has called my phone numerous times. The first 20 calls were either "US government grants" or some Indian guy calling about some vaginal mesh suit for a surgery I never had. Now they are calling saying that they are the irs and I am guilty of tax invasion and if I don't have an attorney an officer will arrive at my house in 30 minutes to arrest me. I called him out on the previous phone calls and he got pissed and called me a stupid lady. Hahaha

This a Pakistan or India based IRS scam. Do not fall for this.

The IRS does not initiate any legal action via phone. Report it also to your local law enforcement agency. The scammers use voice over IP lines (e.g. magicjack (Ymax corporation)). This is against these companys' terms of use and can lead to termination of their contract. However only law enforcement can initiate the contact if you yourself are not a customer. Ultimately this is a case for the FBI legal attache in Islamabad or New Delhi. If you are really annoyed: call or write to your representative in Congress. As these scams happen all over the country maybe this will trigger a reaction (and the NSA can finally be a force for good).

Got a call from this number last night and he left me a voicemail saying I needed to call him back immediately because I am a criminal. although I have a completely clean record....
