sadly a lot of people are exempt ... including charities and opinion poles etc.   As well as anyone you had dealings with or asked for information in the past 2 years, and newspapers I think.

So why do half the people say there was no anwser from the other side

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.

called me in Ottawa . . . left no message . . . .arrrrrrrrrg

calling from colombia, medellin i got cha boys i got a phone call from them and the dude told me he was form medellin colombia and tehy where calling from a contact center or something i got you

I am trying to decide if you are sarcastic or not.... keep doing it this way?  they call and do not leave messages, and many report getting dead air ... this is not the way to get donations ... they are not doing their charity any favours by calling 5 times a day just to harrass people by making them run for a phone and then  no one talks to them

I got a cold call from the CF people in the summer looking for donations .. when I answered the phone, I had a polite person explain what they were doing etc., and I told them to send a truck over ... I emptied my basement and garage of items I had been hanging onto for years .... I would deal with them again simply because they had their name on the display;  talked to me when I answered;  were courteous, and have not called me since then, which I assume means that they realise that they should wait about a year to see if I accumulated more unwanted items.  They also provided their business card when they stopped by with their phone number and web site so I can contact them .... this is how you collect items for a charity ... well done CF :)
