To fix the account issue, You can try to reset the password on the linked EA account that account has been disabled and uses a gmail , and is a different email to what is used on your swtor account (and the ea account your posting on now (so it is not the EA account your posting on now)
The linked ea account used a gmail email address, but is a different email to the swtor email address and the ea account your posting with
use this link (insert the correct Gmail email address into that link) to reset the password then login on that EA account to fix the swtor account for purchasing
This gmail had to of been used on the swtor account previously
