I did all 10 placements and I don't have a rank?

Is that...possible? I've played a lot but I've never heard of somebody just not getting placed after the 10 games. I also didn't think there was some sort of safety net for those who did do poorly in placements. Not that I'd consider this much of a safety net - I went 4 and 6 so with any luck I would have at least gotten a low-ranking silver, but I finished my tenth match today and...nothing.

I'm not heartbroken, I can always do better and that just means that if I really didn't get placed that I have a second chance, I was just expecting to get a rank after the game.
