Calls several times a week but hangs up when I answer.  This unwanted and unwelcome intrusion bothers the elderly lady who is informed in the home.  How can this be stopped?

Check with your phone company.  I am able to block calls by dialing *60 wait for message and then #number#   It will repeat the number back to me and then I hang up.  Try that.  Or whatever your company uses to block calls.

They asked for a donation to cancer survivors and they passed the phone call to someone else to verify that the money would be sent.  I'm not sending any money until I verify they are legit.  They said I had donated before to them and that's not true already.
