All of this is such a sad commentary on society. In case we don't think it works just look at last week's news. The FBI broke up a ring that had bilked Medicare out of 1.4 billion dollars in a kick back operation scamming seniors for medical braces etc. I can't tell you how many times I got that call. We never respond to any phone marketeers for any reason. My husbands response is to lay the phone down and let them chatter until they realized that no one is on the other end and hang up.
