I lost my progress on my original apex account

Okay I originally played on Xbox and the later went on to play on pc. I made a new ea account when I got my pc not knowing I could just link my steam account to the one with my Xbox account on it. Then cross progression was announced and the day before the update I saw a video saying to. Link my steam account or Xbox account I don’t remember at this point to the opposite account that didn’t have it. I did so waited for the next day got home updated and none of my progress from the Xbox account was on the new account. I’ve tried talking to customer support they couldn’t help me much. I think it I’m not mistaken I waited and switched the account back to original idk at this point. But I have my steam and Xbox account on the same account right now I still have all the stuff from the steam account but I was also told that the progress is linked to the account and that I should only have the stuff from my steam account because of how I went about it. But I have the original bundles you could purchase like the one with the mirage skin and the gun and the one pay to win flatline skin with the bones on the side. I’m just confused because why do I only have those cosmetics and not the others I spent a lot of money on. I want to try linking the steam account back to the account it was on but idk what will happen can someone please help I feel so stupid and I just want to be able to access both accounts.
