this number calls over and over but will never leave a message when I call back they say no one is there to answer you call but leave a message to which I said you never leave a message therefore you are now blocked so STOP CALLING

This is a bothersome number.  It is a local number to me but they call frequently; no message left.  Figured it was a wrong number but since they keep calling must be a telesales call or something.

Update to last post.  Just checked caller ID and they have called several times each day for the past few days.  They NEED to leave a message if they expect a response.
