They WILL NOT STOP calling me. I finally answered. They "want to send a free prescription card" or something. So i figure it is either
a) a scam
b) they want you to confirm your address to send you "free stuff," but then wind up subscribing you to some service, and then you will be charged, and forget to cancel it. which should also be known as a scam.
This number just called my cell phone. As I learned long ago, if you answer the phone "Hello" and don't hear anything right away from the other end, then hang up. Because the short delay means there is a computer involved and it is either telemarketing or scammers.
