They have an office in Langley, BC. They've been calling every 2nd day or so. We even faxed them a signed letter last week saying thay have to stop trying to call, and can only continue to communicate in writing (at the address we provided). I heard of this law from section 12 of:

http://consumer.ic.gc.ca/epic/site/oca-c.nsf/en/ca01786e_3.html

We faxed them 3 days ago, and just today they called again. We asked them repeatedly over the phone if they received our fax, and they never said yes or no, just avoided the question, and said, "i don't know". I think these guys are breaking the law.

The first call they made, they came at me with all sorts of threats about having put the claim on my credit report, seizing assets etc.

It is obvious to me that the creditor did not give them the full story.

Their reply to that is they don't vouch for the integrity of their clients, they just want to collect what is owed.
