this number calls everyday, sometimes twice a day but won't leave a message

Didn't pick it up as there was no ID but they call almost every day!

I called the number back.  Mothers against drunk drivers Canada

did not identify what they were calling about

I respect the intent of MADD, not their methods.  Please STOP CALLING!Send me something in the mail, and I might respond when I see a registered charity number. (which, by the way, in Canada MUST have "RR" in the charity registration number, or it could be a NON charity, not-for profit, meaning no tax receipt.  Look it up at the CRA website if in doubt).

I just called them and left a nasty message.   It is the MADD volunteer line.   I called back and you can leave a message.  I left my name and told them never to call me again.   Hope it works.  

caller was female, kept repeating "Hello?"  "Hello?".Very annoying.  I got tired of playing the game, gave a very polite "good-bye", and hung up.I usually don't answer calls of this nature but the phone is for business use as well as private, so I was caught off guard.
