EA Account Locked. HELP!

Hello! I wanted to share this on the forum to see if anyone else had a similar experience or could offer some advice for my current situation. Since 2016, when the EA account was made, I have been using it on PlayStation to play any number of the EA games I purchased. As of recently, I switched systems, and now I am trying to gain access to the old account to carry the decade of game progression over. 

I have the account name, email, and password, but I cannot get past the two-step verification process.  The email not only no longer exists due to it being on a Hotmail account, but it also belongs to a family member who is no longer around. I created a new account to post this, and I hope that I can access the account simply to just change the email address attached to the account.

After speaking with EA support over a chat message, I was asked to prove ownership. I provided an endless amount of details, including IP addresses, ending card numbers, proof of purchases, birthdates, and even more personal info. I was told that after all the info provided, they STILL cannot prove my identity and give me access.

I am beyond DESPERATE and all I want to do is get to my years and years of progress on so many EA games, and I feel stuck. If anyone went through something similar or has advice, I would appreciate anything! Thank you!
