Automated message (called ID Out of Area): I won $2500 vacation in Cancun because I opted in on line (of course, I didn't). I called back and completed automated request to have my number removed. It's always worth a try; they already know I'm a live person because I picked up the phone.
I am registered with the "Do Not Call" and have limited minutes avaqilable on my plan since I am a senior on a fixed income. I use my cell phonw for emergencies only and I resent receiving calls from these unsolicited sources. The "Do Not Call" isting seems to be powerless to stop these calls.
