This caller rang our number frequently sometimes more than once a day and sometimes left a blank message. I finally got tired of it and picked up the phone one day last week (6/3/09) when I was home. The older gentleman claimed to be with the American Legion and wanted a contribution for our troops in Iraq. He was not professional and was pushy in trying to get a credit card number and tried to emulate a telemarketer but failed to even be convincing.
It's the same group of scammers that formally used 2053321947 (Littleton). They say they're raising money for state troopers among other things, but it's all a scam. They won't stop calling. I just pick up and hang up on them everytime when it comes up on the ID.
