Are people allowed to cancel season tickets just now?
But I would guess you’re right, either by simply cancelling the DD without telling the club, or by a special request accepted by the club.
I thought, from posts on here at least, the club have always adopted quite a tough line with cancellations, ie once you'e committed for a season you have to see the payment plans out, assuming you are on the Direct Debit plan, and the only time you can cancel is, essentially, by not renewing.
I had my "You've renewed!" email confirmation on 13th March. I would assume from that time, everyone has been locked in, unless the club are showing understanding and permitting cancellations now, on the quiet at least.
