Account Issues

I've not played battlefield 1 for years, opened it up on my PC's XBOX app and it said I had to link an EA account or something similar, after going through many issues I finally linked it to my XBOX account's email's EA account, and have lost all progress in the game, the account in battlefield 1 shows up as my accounts name which is numbers apparently, e.g. "Welcome back 85570099", how do I get my progress back? I tried general support and the AI chat bot wasn't helpful and I just need to talk to a human please!

Thanks for reading, please help if you can!

you can see the account I'm logged into here I think.
