I also got called by this company in Alberta.  I filed a formal complaint as they are in direct violation of the DNC as they do not honour the ADAD rules as they do not identify who they are or who they are calling on behalf of of a means to call to be taken on their list.

They have been pestering us daily now for weeks.

I tried to file a complaint with the do not call registry but they would not accept my area code (250)
I googled it and found the website has refused certain area codes for years now.

So the "Do Not Call Registry" has effectively blocked taxpayers from bothering them!  

...as we continue with taxes to pay for the website and "Service" and continue to be pestered daily!

Got a call, "are you tired of ....etc. Hung up. Received several calls over last few weeks, usually before checking ID and expecting a different call.  Why can't Chinese hackers pick on Telemarketers!!

Received a call today from this number and did not get a message left. Curious as to its origin.

I did, they only called once, no message. I didn't answer. 519 is a Toronto Canada area code.
