To fix the account for future purchases, You need to reset the password on the linked EA account that has the persona pokazelwa , (not Zellwaa your posting on now) that EA account uses a hotmail.com email
use the following link to reset the password then login on that EA account to fix the swtor account for purchasing
for future purchases, use incognito mode on chrome initially if you purchase on swtor.com to be sure browser cache and cookies is cleared
When i checked they did not have an email from you , resend using the swtor email firstup and let me know and i can check if that email arrives ok , the above needs to be done before gametime can be added though
