Is there a way to report achievment bugs?

I beat all par timers, even got the achievment for beating all par timers and didn’t get Generous Tipper unlocked (the achievment for beating Tip of the Spear par time)
and today I beat Long Night of Solace on legendary above par score (like 79k points) and didn’t get any progress, it also didn’t register on my mission overview.
Tried relogging, didn’t work.

I’m really tired of this, it’s not the first time it happens and it’s draining all my will to finish camp on legendary.
