lost all my cosmetics after merging

When cross progression first came out I was going to link my accounts together but I had 2 separate EA accounts with 2 of my accounts one was for switch, the other was for Xbox. I unlinked 1 of my platform accounts to my this ea account. When I logged on to apex I had an error where I couldn’t access any of the in game tabs no legends or the battle pass. And all of my cosmetics were gone including my heirloom but I still had my stats. Disappointed after losing my skins and heirloom. I stopped playing for a month and after that month I got on apex again to see if I had gotten my stuff back. For some reason the game gave me the cross progression prompt. After that I thought I had gotten all of my skins back but I had gotten something else. I somehow gotten 200k legend tokens and about 300 packs and around 500 apex coins when I logged on but still none of my cosmetics were there. I was hoping there’s a chance I can get my stuff back and perhaps my heirloom.
