Account Shows "Does Not Exist"

Hello everyone, I’m in desperate need of help with my EA account issue—I’ve tried contacting support but haven’t gotten a solution yet, so I’m reaching out to the community hoping someone can guide me or EA staff can see this.

Here’s the full situation:

1. My original EA account suddenly started showing "Incorrect password" when I tried to log in. I thought I might have entered the wrong password, so I immediately tried to reset my password. However, when I attempted to recover my password by entering my registered email, phone number, or even my EA ID, the system consistently showed "Account does not exist". I can’t access it through the EA App, the official EA website, or any other EA platform—every attempt to log in or recover the password results in the same frustrating error message.
2. This account is linked to my Steam account. When I tried to launch Apex Legends via Steam today, it showed that my EA account (the original one) is banned. This is confusing because I can’t even log into the EA platform to check the ban reason, appeal, or verify any details—since the account is "non-existent" on EA’s end.
3. I have important in-game purchases and top-ups on this original account: I’ve made multiple in-game purchases for Apex Legends over time. All my game progress, skins, and top-up records are tied to this account, which I’ve been using for a long time, and losing access to it means losing everything I’ve invested.
4. I had to register this new EA account just to post this求助 and communicate with support, because my original account is completely inaccessible.

I’m really confused and frustrated—how can an account be banned on Steam but show "does not exist" on EA’s own platforms? I didn’t violate any EA or Apex Legends terms of service, and I have no idea why this happened.

Does anyone have a similar experience? Or can EA support staff help me verify my original account, check the ban status, and recover my account? I can provide any necessary information (like purchase receipts, account email, Steam link proof) to prove ownership.

Thank you so much for any help or guidance—this account means a lot to me, and I don’t want to lose all my progress and purchases.
