I just did what Mark did - almost too easy and hopefully no more annoying callings.  Honestly - no worries about calling - (416) 736-0699

I've also been recieving calls from this number.  The company is called Actions Windows and Door's Ltd.  I googled them and got their info.  I called  and asked to be taken off the marketing list.  Here's the info:
Happy Hunting!

Action Windows and Doors Ltd
25 Milvan Dr

(416) 663-7173

Thanks for the information. Similar situation to those above, got a marketing call from a windows and doors place. I am normally quite polite and patient with telephone solicitors. This guy was so idiotic that I actually lost patience. Thanks to "Ladies and gents I give you the Answer - 28 Jan 2008" for the contact information. I called the number and spoke to Dillon's replacement. They said they would take me off the list.

incessant calls from this number, all hours.

I live in Barrie and am getting these calls 4 times a day, work nights so extremely irritated by calls with no one on the other end 4 times a day.  Hard enough to sleep in daylight.  Called the police but said they can't do anything about it.  Cannot call TO police as they said not in their jurisdiction as live in Barrie.  Anyone else outside of Toronto getting these calls.

Pls trace out this caller ID for me.
