Ticket master registration

Heard nothing but praise concerning the smooth process following the recent email. As per usual when I get down to doing mine it ends up a pantomime. I have a season ticket as does my 14 year old granddaughter. My granddaughters is registered in my account. I register myself seamlessly onto the new ticket master account, log in and now follow instructions to add my daughters client code which successfully adds her to my account. So far so good. Now the issue. I get an option to select “manage” so I can manage the purchase of her season tickets and other game tickets. I click option which now states it will send her an email with a link for her to give me consent. Problem 1 is she has never had email registered with the club. So I ring ticket office. Resolution he said was to use my email address for her then I would get the link so effectively I could give permission. He registers her to my email account, call ends. I click link in ticket master account and hey presto as he stated I received link in my email requesting permission,unfortunately for her to give this she is instructed to login to her ticket mater account, go to my network and accept or decline. She obviously hasn’t got just said account. Call 2……same advisor tries for 20 mins to resolve this giving me permission to manage her account by trying to input it manually at his end. Eventually gives up as he can’t find a work around. Advises me to come to ticket office and hopefully they can resolve it. What a pain…….not confident they can.
