These people really make me angry!  They are calling to respond to an inquiry from someone at this number who saw an ad on tv and requested a call back.  You MUST be on Medicare.  They are counting on people not remembering whether or not they called, or maybe someone else called and wanted it. They are counting on confusion among the elderly.  They are a scam and participating in taking advantage of those who are unable to recall what they have done in the past.  May they all go bankrupt and suffer from back and leg pain so they know that their worthless products won't help them
