We have been on the list for years. Sometimes it works, sometimes not. When I do pick up and get a live person, as soon as I say, "You know you are not supposed to...", they hang up. The worst is the ones that hit our fax machine! What a waste (and expense) of paper! I've now been getting calls from a "disease" research wanting money. They call late at night and early in the morning! Very frustrating. We do not pick up any calls that we don't know but they keep calling.
If you are on the list and still get calls, report them to your State Attorney General's office.
