Again. Were you sent back a few levels or all the way back to level 1? If level 1 then what is your GT?
They need to fix this now or im quiting cod, i have been playing day to get to 9th prestige and i get deranked
you don't get reset for no reason. you only get reset if you do something that violates the TOS like excess use of foul language, hacking, having an offensive emblem, playing in a modded lobby or boosting. odds are you were reset for one of those reasons.
Get of your high hourse and do you research. Some people have accidentally been reset due to a glitch.
People have lost a few levels do to.a glitch but no one has been completely reset. If the OP was 9th prestige I'm going to assume he he did the prestige glitch and got reset for doing so.
