Caller claims to be a "Federal Attorney" that can barely speak plain english and is definitely indian. Claiming to be from the Fedearl Financial Crime Investigation unit of the Federal Government. I know they are lying and refuse to give any additional information. I called several times to see if I could get information out of them and one of them finally gives me this information:

Jeffery Joel Brown
11701 Chullovista Dr
San Francisco, CA 94102
424-672-2205

I will forward this information over to the Federal Trade Commission fraud unit

They called me as well, I have a voice mail that I have not deleted from "Kevin Collins" who told me the same thing and also stated that criminal charges were going to be filed against me.  I challenged him on that statement and he became flustered. Eventually he told me he works for "Roy King" at the same number, but that I had to call back to talk to Mr King.  I called and spoke to Mr King, who after calling me an idiot proceeded to deliver a string of obsceniies about what I should do to myself. I called back several times and each time Mr King became more aggressive.

I received several calls from this number and, I have a voice mail that I have not deleted from "Kevin Collins" who told me that he was a paralegal for.

BEWARE!
This is one of MANY numbers for YMax Communications Corporation

I Googled YMax Communications, and they are the #1 worst source of SCAM complaints on the ComplaintsBoard.Com website.

According to many of the complaints posted, they lie about everything to get you to give them money (like saying that you've been named in a lawsuit, or claiming that they represent the IRS, or offering ‘Free Government Grant money’ to recently-arrived foreigners, etc).  

One complainer said the people they spoke with at YMax had heavy Indian or Pakistani accents, so they might be based beyond the reach of American laws and have the phone calls transferred to them.

Based solely on my web research (and not on any personal experience), this is probably the worst telephone scamming operation I've ever learned about...
