I used to have the Unyelding ornament for the Oathkeeper but I didn t played for a week and when i started to play again it was missing. I reported it to bungie but they only said I don t had it. But I did. At that week i logged in to the companion and it was there but for some reason I couldn t equip it.

Do you have any proof that you previously had it? If you filled out the missing items report & they then said you never had it, then it would seem that you never had it and/or mistaking it for another item.
