Lost Account Progress

I have been trying to restore my xbox account progression for around 2 years no with no luck. I think the original problem was that I unlinked my xbox from the original EA account and linked it to a different account. I have finally revisited the issue and relinked this xbox account to the original EA account but have seen no results. EA support (including advisors) have currently been unsuccessful in restoring the account and have pointed me to these forums for help. Is there anything that can be done. I have seen online that people have gotten their accounts to work by getting devs to delete their PC progress to restore their console progress but I was unable to get the EA support team to do it (hence why they pointed me here). I would really appreciate all the help I could get on this matter.
