Who called from 9712201490

On April 30, 2012 at 9:39am I recieved a call from a cell phone 1 971 220 1490.I did not recognize. It  When I called the number  19712201490 , a very young recorded voice anwered," this is NET TALK U.S.- enter your number and pin."  absolutely stupid and so immature, but someone out there will fall for this evident SCAM.

This company keeps calling harassing after I asked them to stop and out on do not call

I have stopped  answering any and all calls that come in without a name, or those I do not know like this Jules Verney. I delete all these calls.

I pressed one to talk to someone.  Then I said, "Hi, I am wondering why I received this call since I do not own any credit cards".  They hung up and have yet to call me back.
