This person calls often and does not say anything or leave a message.
This is quite annoying and would like it to stop.

Calls me two to three times a month. Never leaves a message, if I pick up there is no one there.I have repeatedly emailed, called and even written in to the Canadian Diabetes Assoc. asking them to please take me off their call list, but never even received a reply back.This has been going on for over a year now.

I too have been called almost daily from this number with message,and no one on the line so I searched it - The Canadian Diabetes Association number came up.  I understand the negative impact it has on people (me included) and how badly it reflects the CDA as a whole.  As a mother of a young daughter with type 1 diabetes I am saddened about the bad practices of the CDA clothesline segment of the CDA which undoubtedly paints the entire association in bad light.  The CDA has researched and published many educational materials for parents, schools and caregivers of children with type 1 diabetes.  They also do outreach to newly diagnosed families, among other beneficial practices.  The work that the association as a whole does has been invaluable to our daughter and family as a whole.  I write this only to highlight that the Canadian Diabetes Association does very important and life-saving work and the practices of the clothesline division of this association does not reflect the good work that the CDA does as a whole.  I will be contacting the CDA over the annoying perpetual calls and voice my concerns on the impact they are having on the association as a whole.

This IS the Canadian Diabetes Foundation. I gave them my number (& allowed them to call me) because I am a regular contributor  to the CDF. You may request that your number be removed from their database, but that might not be sufficient.I do not know about the DNC (Do Not Call) rules precisely, but many (meaning LOTS) of DNC requests have resulted in my getting calls from other telemarketing a-holes. In this case....... caveat emptor .... Let the buyer beware...There are too many ways for a biz to circumvent federal rules such as Do Not Call. Since I use a cell phone as my primary phone connection, I have ID'd this number as "CDA Spam". Thus, if called, I do not answer. (or do, if I have a donation on hand) Easy. For me, at least... (btw, I am a Fido customer)

I get a call from this number every day. They never leave a message and I have no idea who they are.

Keep getting calls from (613) 746-4633 almost daily. Name unknown but someone definitely hangs up after listening to me say "hello" several times.
