Can’t Unlink Dragon Age Inquisition Tapestry Account from Defunct Email.

I made a tapestry account back in college years ago and I never got around to playing it. I recently played through two and origins and now I’m trying to upload a tapestry I made recently, but I can’t link it to my Xbox because the email previously used is inaccessible to me. Chat Help hasn’t been helpful and I can’t create a new ticket. Any ideas people? I can try to just play the game without Tapestry, but i don’t want to miss out on a unique experience.
