Other than reporting the number to your local police department, there is nothing you can do.

If the number starts with "876", those are what I call my Jamaican buddies!

No matter what you say to them or yell at them, they carry on with their whole speech completely ignoring you.  There is actually a hot line now where I live referring people to report as much information as they can get from these guys to their local police department.

You can't block them, get rid of them, or anything.  So, you might as well have some fun with it.

My husband carries on messing them and gives them the police department's phone number as his own number.  He's so funny that the guy one time asked why there is someone laughing in the background.  He said it was his children playing Playstation 2, "do you have a Playstation 2", "isn't it great?", blah, blah, blah.  He even had the guy talking about wrestling one time!

The Jamaican scammers will change around who they say they are with too--UPS, FBI, Fedex, company names, sweepstakes companies, etc.

Here's more information on phone scams:

However, the last time I read, emails and phone calls from outside the country have been impossible for the government to stop.  I believe this falls under the jurisdiction of the Interpol; and, last I read, they weren't taking up this cause.  So, I have no idea what progress, if any, the Attorney General has made with international scammers to date.

I just got a call from a company and the caller was a lady saying that I won a "$250.00 shopping certificate for Wal-mart" and that my credit card company gave them my phone number. She then stated that I won 6 different magazines and all I would have to do is pay the shipping cost (Red flag - NEVER pay shipping cost). Then she sent me to her supervisor - he went over the same spiel, then he asked me to verify my c.c. exp. date.... THEN he had the guts to ask me for my c.c. #. That's when I said "I never give out my c.c. info. and my c.c. company knows that I am still a member." So I said "Have a good day" & I hung up.
Their phone number is 423-581-5397 - they call themselves "Publishers" (not clearing house). I wanted to share this with all of my sweepsadvantage friends & keep them from getting scammed.  I immediately called my c.c. co. & asked them about it and they assured me that they did not give my info. to any second party company.
