There's an option for a cash refund on season tickets.
"Should you instead opt for a cash refund, you will receive a pro-rata cash refund and will forego your status as a Season Ticket Holder, along with associated benefits. You can do so from Monday 15th June at 2pm"
They could/should have put it under an 'Option 3'.
You should be able to request the cash refund and then watch the games on your iFollow subscription.
