I have got 3 such calls in 2 months. This was a second call (left voice message) that claimed to be from federal crime investigation department. The person had a heavy accent.He asked me to call back on 202.800.8489.
Some guy with a Lisp called and left a message saying his name was Officer Jordan Lopez from the Fed Crime investigation Unit. Threatened legal charges pending against my father if he doesn't return the call to 202-800-8489. Tried to sound very serious...
This is the 4th call of that nature that I have received in the past 2 months. Every time from a different phone number but the caller always has a very strong accent. I don't pick up these calls. I just listen to the message they leave. I don't know why nobody is doing anything to stop this.
I have too received many prank phone calls from this same guy on many occasions. You can file your complaints to local your county police online in the Financial Crimes section as i have and hopefully this problem gets resolved.
