The football club have released a statement

The football club are currently experiencing challenges with our finance provider, Zebra Finance. In light of these challenges Zebra Finance are unable to accept any new finance applications for 2019/20 Season Tickets. All applications which have been made through Zebra Finance for 2019/20 Season Tickets remain valid and no action is required. 
The club is currently working hard to resolve these issues and will update in due course. 
UPDATE (28/03 - 9pm)
We continue to explore possible finance alternatives and we ask any supporter who has yet to complete their Zebra Finance application to fill in this short form to be kept updated.
