These lowlife scum keep calling from a variety of numbers.  They pretend to be selling a miracle pain cure, but are trying to get medical insurance information.  Am guessing that this is the latest scam from the card service scammers (as we stopped getting daily credit card scam calls, and now get these).  The scammers have a nice smooth script that they use, and they sound pretty legit (better than some of the more idiotic scams).   As always, these are simply thieves looking for information so that they can ..???? (must be related to drugs, because they are specifically interested in information for your medical insurance relating to drug coverage).   Obviously, no one is stopping the scammers from doing whatever they wish.  If it isn't one scam type calling, it is 10 others.
