Just put in my details to see how much it would cost to renew my and the daughter's season ticket.
At the end of the process, it gives me the total price for both tickets and the option to use my credit note against the purchase, but that is where the fault lies. There is no option to use the credit from my daughter's ST against my purchase, despite the fact that I correctly selected her from the Friends and Family list and I have always purchased her and my STs together in the same transaction for the last 10 years.
Guess it will mean having to call the ticket office - proving that the new system is not as great as they would have you believe !!
