Yeah I'm one of the people calling you from this number. We only call you if you've left your number after speaking with one of our canvassers on the street. Trust me when I say we don't want to be calling you if you're not interested.
Easiest way to get us to stop calling, just pick up the phone and let us know.
If you called 3 times, and no one answers, then that's a good indication that the party isn't interested in talking to you. So remove the phone number from your automated dialing list.
