Why answer these calls, where you don't recognize the number.  You know it's someone calling to scam you out of money.  With emails, if the subject line doesn't apply to my needs, I simply it delete.  Sounds simple, but it works for me and I don't have to deal with the garbage.

unwanted call, phone not working, repeated calls.

I just now had a call from this number which shows on my CALLER id.........let it ring 5 times and then decided to pick up the phone, said 'hello' and THEY HUNG UP.  They can kill my "you know what".

They called my house, with the caller ID Dealer Services. I let the phone ring and then i finally picked it up and said hello. They hung up in my face. If they call again I will give their number to the police I'm getting sick of this. This is the third time they have done this

Called but left no message, because they couldn't.  I have no landline, so they can only call my cell.  I have an app on my smart phone (Mr. Number) that identifies them as solicitors.  When the call comes in, the app receives the call and immediately hangs up without even ringing.
