Callsign not showing waw prestige 10

I just got hacked to 10th in waw and it's not showing in the mw3 callsign

 

The callsign doesnt updated straight away, it takes 24-48 hours to update

 

Thanks it's just that I got 10th also in mw2 and it showed up right away.

 

You do have to go into multiplayer kill someone finish the game for it to update on MW3.

 

K I've done all of these but I think the lobby wasn't legit because I've noticed I still have the same challenges completed when I was 1st prestige, it's also not showing up for my friends and he has his same challenges, and last it involved joining a lobby and starting up a split screen game. I want to know if anyone can derank me and then give me 10th.

 

I can rank you. You will have to follow the rules carefully. PM me your gamertag.

 

K thanks

 

waw is an older game servers are is realy old il update just takes time

 

But the lobby I was in probaly wasn't legit
