someone could make a million selling an item to block these calls.  Who is AAS?

This is direct sales company. They want to sell some sort or air purifiers and vacuums.  Did you answer a survey at your door about local air quality? Yeah this is them.They called me for days on end and when I finally called them back and asked to be taken off their call list, the girl went into a long sales blurb, telling me I'd won some crap.  Finally I asked to have my name taken off their list and the response was "Sorry Chris, we're going to call you forever!" and she hung up on me.  The calls haven't stopped.

Advanced Air Supply 12-626 Esquimalt Rd, Victoria, BC V9A 3L4

Why don't you block the number,  I just did.
