How can I stop these annoying calls? Other than ripping the phone off the wall.

scam
"one of 5 prizes can be yours, all you need do is pay shipping or go to a workshop selling high price timeshares" report to bbb"
gave me this number as number of supervisor to talk to regarding getting calls stopped.
supervisor name is janet.

I keep getting calls.  The one time there was a "Hello?  Hello?" message from some stupid slag with an oriental accent on my machine.  I'm on a "Do not call list".  Stupid cow.  It's obviously an answering machine.

(778) 786-8589 can f*ckoff and die a horrible f****ng death

Got a missed call from this number.
