Broken Rank Advancement

Same problem here with me!!!!!!

I just bought the game this week after having played BF3 & 4 for years. I'm rank 9 Recon and I haven't unlocked the Gewehr 95M yet, which I was supposed to unlock at rank 6... 

Also I'm rank 10 support and still have't unlocked the Bren gun yet, supposed to have unlocked it at rank 8. 

What an absolute joke. 

What's the point in even playing the game when all the customisation is crazily overpriced with company coins(6000 cc to change the camo of your uniform to suit the map/envrioment!) and then to top it off in order to get company coins you have to complete assignments and specific tasks in games, oh wait they don't register and count your progress because that's broken too. So the only thing that you can easily progress towards, weapons, and unlock just by playing the game casually(I.E. you aren't going out of your way into crazy/stupid scenarios to "kill 3 enemies with 1 grenade whilst capturing objectives") isn't possible because you don't get rewarded with the weapons as you progress because the game is broken and they don't care about fixing it because they know some people get angry at these problems and then the only option left is to buy their items/weapons with real money through micro transactions.
