Issues after Cross Progression is activated on your account? Check here first!

Hello. I had an issue with my apex legends account. About 1-2 months ago I tried to link my ps4 account to my pc account, and the ps4 account was my main. I had initially a problem logging in my account so I changed my email around the email and i think i unlinked ps4 and i think i lost all my progress on the account. Now i currently have my pc account which is linked to steam so it has my steam name. My ps4 account had about the equivelent of lvl 700 with a ton of cosmetics and a heirloom with the psn tag King_sanicmlg222 (it may also be King_Sanicmlg222). I am pretty sure it is because of my attempt to changed the mail that i may have lost the progress on the account but i sincerely hope to regain all of my old items.

I really hope i can get my items back because i lost about 1800 hours worth of content , cosmetics and limited time cosmetics. If not that`s ok.
