person said he was from Canada revenue agency and that I was undervervue and to phone (613) 699-2403

Knew my name and last name. I declined, since she didn't identify herself or the nature of the call. Say's she'll call back another time. Most likely some sort of collections. Ugh. (250) 714-0921

who is this

I just got a ring from this number, which means this punk is doing random cold calls because, you see, no one actually has my cel#. Nice to see my suspicion is right here!

Automated voice said this is a call from Westjet and that my latest flight was selected to receive $999 dollars. Press 1 for more details.  I havent' taken a westjet flight in months.  I hung up.

I got the same thing. They re route your call,  and the device even says so

Just got a call this morning, robot message said I won a free night's stay at a Hilton hotel.  I had just entered a door prize contest to win exactly this the day before, thought it was legit.  Got put thru to a very sketcy/noisy call center who started asking for info. I hung up without giving them anything.  Don't answer calls from this number.
