They keep calling my cell phone over and over again.  Please stop calling.

This person calls about cutting grass, its Doctor grass... he constantly calls about twice a day.... how do I get ride of this inconvenience..

I continously get calls from (905) 525-1223 (Dr.Green Lawn) and most of the times when I pick up no one on the other end says anything then the phone goes dead.  I called Bell to get call screening to block the call and guess what I am unable to block this number - how convenient for Dr. Green Lawn.  I have just sent an email to Dr. Green Lawn to stop calling my home number.  If they don't stop calling I may start dialing there 1-+1 877-374-7336 number and not say anything and hang up on them as many times as they do it to me.  I figure if their phone lines get tied up they can't be selling and if you affect their ability to generate revenue this may be an impact to get them to listen to complaints.

Nuisance Call - they hang up after my message voice comes on and I hear lots of background noise, then they hang up
