Replying to Broken Zipper Help (Saga Shutout)

So I recently (mid-december) got a Saga Shutout jacket. It's sick. But, after wearing it but once, the zipper decided to shit the bed.
Most of the time when I pull it up, one side of the teeth goes under the other side. Sometimes the zipper zips but then it just falls out after a slight tug.
BUT, I know it's not totally busted because I can, on rare occasions, get it to work.

So anyone have any thoughts/suggestions as to what I should do? There any remedies out there that anyone knows?

Thanks!
I really love this coat and don't want to have this ruin it.

On a side note, to anyone else who has the coat, is it just mine or do all the coats have a headphone port on the inner mesh that leads nowhere? Like to no pocket or anything, just to in between the mesh lining and the shell.

Oh and +k, obvi
