rank got reset

Seriously? I was a 19 and my rank went all the way down to a 1. What the hell did I do to deserve a rank reset? Did this happen to anyone else??

I Was A Rank 9 And Got Reset To 1 Twice So I Stopped Playing H2:Anniversary MP Now All I Play Is Big Team Slayer.

Mine got reset as well and gets reset all the time to be honest. Been that way since the game came out. Was just looking to see if others are having he same problem. I was a 7 In doubles just the other day… I can never get above 20 I just keep getting reset.
