Funny you should say that ... You're posting on here as well. I work for an agency who takes care of these types of calls. My job is to search reported numbers from all blog sites. So, the answer to your post is YES these postings work.
I messed up and filled out the online Dollar General sweepstakes entry to win $1000. In order to be entered, I had to wade thru several pages of questions. Most I answered no, but one was "Do you own a car?", and I said yes. Big Mistake.
9/04 13:07 2nd call today from this group, only difference is #. Don't know who they are or what they want, what I want is for them to stop bothering me!! Previous call was from 951-266-5507. Even with a call blocker that allows 1200 blocks, how do we defend ourselves from the proliferation of scammers, spammers and con artists?
