they call me 7 times yesterday, even 9:10pm; and 4 times this morning already.
Can I sue them telephone harassment?

Called me more than once. Planning to call back to be remove from their list. Hoping to be as lucky as "no" has been. If not, I will report this caller at https://lnnte-dncl.gc.ca/plt-cmp-eng. I also had been on the DO NOT CALL LIST for a while and even though I still receive telemarketers' calls.

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

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

the what wre you doing here....LOSER

I answer this one.  As stated it's to pick up donations that us lazy bastards can't be bothered to drop off anywhere :).  I'm not a fan of unknown numbers, but please reconsider for this one.Take care, j
