They are supposed to mail one, I haven't gotten mine either, I did mine almost 2 weeks ago as well (Dec.5 is when I took my exam to the MNR).
I emailed them Dec. 6, as I found they had my mailing address wrong when I logged in online, and they told me it wasn't sent out yet, and they could see my new correct address, and my card will get sent there. Unless they ended up sending it to the wrong address LOL!
