This! - It's stupid! I had a real issue trying to renew mine & my daughter's season ticket last year as it had separated her ticket from mine onto her own account. I then needed 'permission' off her to link my account to hers. Ok, no problem, logged onto her 'new' account, as it was still using my email address, & gave myself permission to buy tickets for her. No problem, or so I thought!
So, credit card in hand, I went to log back into my account.... "This email address is already in use". What??
So, I've now been locked out of my own account because it has asigned my email address to her and hers only account!
Right! Back into her account and change details so it uses my work email address - then back to mine to log in and link accounts again. But hey, that's progress!!
