Its recycling matters. They come and pick up used clothes and books and other items that can be distributed to people in need.

Over the years I've donated a lot of stuff.

Unfortunately, the last few times they've called and made arrangements no one has appeared at my house to pick up the stuff they asked for.

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

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

They are in fact a charity that is calling to ask if you have anything to donate so they can come and pick them up.  The phones are staffed by volunteers that are often new canadians and young so they can be hard to understand.  They are trying to do good, answer and if you don't want them to call you anymore, be polite and they will definitely respect your wishes and remove you from their lists.

This company is Recycling Matters.  They have be calling me for months and I have told them numerous times to stop calling me.  It stopped about a month ago. They called me twice on yesterday and once this morning.  Now they they are using a new tactic by hiding behind a charity, Save the Children,  as an excuse to call people because charities are exempt from the 'do not call list'.  Do the citizens of this country have no rights against these pests and parasites?

Yep, this stupid caller call my number very often too.
