2 unknown calls in the last week from 604-630-96xx to our cell phone.  Calls came in around 2pm (Sunday) & 6 pm (Thursday).
No messages.  Last call, went to our cell's voicemail, could just hear the click of someone hanging up.

Called the #, it is a draw from "Point to Point Destinations" offering a trip for 2 to Vegas via WestJet as their tag-line.  We had entered a draw in a mall a couple weeks back & posted our cell #.  Spoke to sales rep named Jen & asked if she could remove our name/# since this wouldn't apply to us, we have a similar membership deal elsewhere.  Gave her my first name, she also asked for my last name in order to reference for removal.  I gave her the first 3 letters of our last name & our cell #.  We'll see what happens.

they called, I answered they made some kind of grudge type(throaty) noise and hung up.
