Re: i dont get the unlocks from the story

I have recently finished campaign to unlock "To Valhalla" assignment. Unfortunately, the assignment medal only blinked on my screen during the closing cutscene but it didn't (and still doesn't) mark as finished in assignments tab in menu. I recieved the EA app achievement for finishing campaign with the correct ending for getting "To Valhalla" assignment and unlocking QBZ-95-1, however I hadn't recieved them in game and there is NOTHING I could do to fix it. I have tried all the solutions suggested by EA and players (joining multiplayer game after finishing campaign and staying in the match till it ends, redoing the final quest and the whole campaign after restarting my system, repairing game files by EA app and replaying the game, reinstalling the game and replaying it, I even tried running the campaign by starting it via Battlelog with no effect whatsoever) even the support isn't able to help me, because tools for manually granting players with in-game rewards are not available to them.  I was suggested to describe my problem on this forum even though others already did it and the solutions mentioned were useless for some of them too. I would like to add that I'm playing on PC. I'd be glad if anyone from EA BF4 Devteam (if it still exists) would be informed about the issue.
