EA/Xbox Account Linking Issue

I had never had an issue until BF6 Beta launched, and attempted to login to several EA games on my Xbox Series S, however, it asked for a code, and it was attached to a random email I have never seen or heard of, and an old number I utilized previously that I no longer have access to.

I’ve attempted to reach out to live chat support and open a case, but when I do get an agent, I get disconnected and I get an email from that support agent stating they couldn’t reach me, and this has occurred numerous times.

Any solutions for this?
