First time this number called me. Did not leave any voicemail.

Please do not call my number again

they are a non-profit/charitable organization - according to the DNC-list these organizations are still permitted to call

multiple calls, never a message

Repeated calls, but never a message left.

I thought it was against telemarketing companies to call without identifying themselves.  Dead air is all I keep getting and I refuse to answer another call from these pests.....I get 4 or 5 calls from them a day.  I am going to report them to the CRTC for not practicing fare telephone soliciting practices.
Bloody hell, I hate it....STOP
