Calls all hours - when you call back, it offers to let you delete your number from their faxing list but then requires an extension, which of course I don't have....

Today I've received 6 calls from that number.  It's a fax. I've finally connected my modem in order to receive the fax.  The name of the company is Canadian Trade Index.  There is a toll free phone number : 1-+1 877-463-6284.  I called and I leave a message telling them not to continue.  I hope it will work.  I goggled my phone number and I realize that somebody else had my number as it fax number in the past ! I owned that number for 5 years ! (Excuse my english, it's not my mother tongue)

Removing your number from the list is really a 'confirmation' that your number exists.  There is no motivation for the sender to stop.  This isn't new spam, but it is persistent.  Called my telephone company a year ago about the annoyance.  I still get calls.  Hopefully, this fall, when the new "do not call" database is in place for the nation, junk like this will stop.

I receive calls from this fax nmber at my office at montréal

Once is asks for an extention enter 00000 and then it will ask for the 10 digit number.. once you enter it .. it will confirm it has been romoved.

Finished typing this note and it phoned another 10 times.  If you just hang up, it calls back immediately.
