i dont get the unlocks from the story

Hi there! 

So the problem I am encountering is that I have done the campaign numerous times, and did all three endings (won't state specifics on the off chance someone is playing it for the first time) and I am yet to get not only the three weapons, but weapons such as the shank despite completing the objective to get it.

I have tried launching the campaign right from the Battlelog website as well, but no matter how many times I do, it never says I complete any of the missions on Battlelog. As of now, it says I haven't even started the campaign, despite having the achievements on Steam and EA. 

I tried reaching out to EA Support about this issue and was told to wait, which I had no problem doing. It has been almost two weeks now, and I have gotten nothing. Is there a way to either fix this sync issue, or get it to register that I am doing what needs to be done for the unlocks? 

Any help would be HIGHLY appreciated!
