Battlefield 4: Single Player Campaign Progress Not Saving

I'm having the same problem.

I literally finished the M249 and P90 endings in ONE play-through because I lost my save, twice before. I got the achievements for beating the final mission twice, but the game didn't save ANY of it, and now I'm stuck starting over from Baku. It's right there in my damn activity feed, but the save (and therefore medals/tags/MP guns)  is gone.  It's bullcrap and they won't fix it. I wouldn't waste my time, honestly.
