Hey RogueEmporer243,
While I see you mention only ever having one EA or Apex account, if you've been playing on Xbox this entire time there's definitely another account out there as well.
The account you're posting with had only accessed Apex on PS4 and PC in the past, so if you've ever played on Xbox before, it was on a different EA account. Progress is stored on the EA account level, not on individual platforms like PlayStation, Xbox, Steam, etc. This is why you wouldn't be seeing the progress you're expecting.
Progress cannot be transferred across EA accounts, so the only way to try restoring access to the progress you're missing would be to re-link your Xbox account back to whichever other EA account was used in the past. We aren't able to guarantee it would restore all progress due to how the unlinking system works, but that will be the best way to try and restore any missing progress from what you remember.
We are not able to make any changes to your account status or progress via the forums, but if something was linked or unlinked incorrectly it may be worth contacting support to see if the original platform can be re-linked.
