My apex account 100% with over £1500 of transactions got “permanently lost”

This also just happened to me as well. Made the mistake of linking my Steam and PSN accounts under the wrong EA account, waited 6 months, linked them both under the correct one, and boom everything is gone. It gave me a fresh account and gave me "thank you" prompts for purchasing old packs I did years ago and even gave me 600 apex coins from those packs. I dont think there is any way to get our old accounts back the way its all set up.
