Re: Game said im not rank 10 but im rank 75

This is based on a few different factors.  For example, if you played on previous gen, and you transferred to current gen and did not transfer everything over, it would make you start from the begnning.  If Battlelog shows you are rank 75 and the game shows you are rank 10, then its a sync issue between battle log and your soldier and you have to wait for it to sync.  Whatever battlelog shows you is actually correct.

If you contact support they can tell you what your rank should be, but generally what BL shows you., not your game is correct.
