I used to be with BT some time ago. Recently took out a new contract which went active a few days ago. However, when I log into my account t using the email address registered to my new account, it only bring up my old account. Even though BT are clearly aware I now have a new contract as they are emailing me on the same email address. Also, when I try to claim my voucher, it brings up my old account and new account. When I click on the new account to claim my reward, it just loads a blank screen. Not having much luck lol! Any help would be appreciated.
Try contacting billing using message now and they will help remove old account.
