It's the diabetes looking for collections, clothes etc....

These guys (telemarketers) pretend to be a charity, but in fact are a big business making profits from your used clothing and items.  Everyone involved along the line from the person calling you, to the driver, to the store-front (Value Village) selling your used items makes money.  Say your old jeans sell for $15, only $0.25 goes to charity.  Give to a true charity like the SALVATION ARMY - they only have volunteers and don't inflate prices for the needy.  Value Village is a for-profit-organization from the USA.  The main owners are Tom Ellison, son of the founder Bill Ellison, and Freeman Spogli & Co. a private equity company.

If this is such a deserving charity, why is the name not displayed via caller id and why to they call me 2-3 times a day every day? I have previously answered their call and listened to the pitch and politely said no, yet they keep calling.

This number is the Canadian Diabetes Clothesline pickup.  They are not telemarketers and NOT a scam.   I give to them regularly,

It's the Canadian Diabetes - Clothesline Program...

Robo calls with no one on the other end, up to 10 times a day, and the regulators don't seem to care.
