call me a few times.

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.

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.

Recycling MattersWe've given several times and had no problem with pick ups.It helps when you give.

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

This number calls me fairly often.  Generally, I don't answer and there has never been a message.  Today I answered, but there was no one on the other end.  Very frustrating!
