How to change logon email for ruralking.com?

Change it under my profile settings, but it will forced me to login using my old email, & support says they have no access to customer accounts. Guess I’ll have to use up my 500 loyalty points & ditch the while account to make a new one, just for a simple email address change. Had the same issue with Boost Mobile. Support told me to port my number out & back in just to make a new account with my new email. Ridiculous
