I got a call from 3219874591 AGAIN today (4/01/2011). Also get calls from 3219604500 every day same crap - i don't answer, just add them to the phone book as As* Ho**e #x so it shows on the display when the call comes in and I can cancel it. My number is on the do not call list. Now there are two spammers calling me daily - will soon have to abandon this phone number to get away from this crap. Whey don't i have the option to block senders by number on my GO phone??? (The correct answer is that AT&T likes having you lose you prepaid cell phone account money to scammers.........)

Received a call from this number on cell phone.....they left a message of hi,
then hung up. Seems like I get these everyday.

I get calls from these guys every other day. They use to call my home phone on their cell phone which is how I knew it was a prank call. They stopped when I threatened to reveal their number to the police and then they decided to do the same thing to my cell phone number. I don't know how they get it. And it always seems to be a different person on the line even though it is the exact same message. Also, YOU CAN NEVER CALL THEM BACK. It always just says the user is not available to take messages at the time and does not allow any voice messages to be sent to that number. I filed a report a few minutes ago and have yet to hear anything.
