Got a text message from this number saying I won $1000 gift card from wal mart and to go to a website to claim it. I did a reverse search and tried calling it but nothing came up and the voicemail is not set up according to the operator.

Went to the website on a secured computer (http://walmartgift.mobi) which brought me to www.websurvey.info (or something to that effect) where it asked for my name, address, phone number + additional info but I stopped reading and closed the window.

I also live in Toronto, Canada.
Super sketchy!

Got the same message as above.  I also closed the window.
