You're taking out of your backside mate. You have no idea whether he's been offered deferred seats but you've jumped to a conclusion without any evidence whatsoever.
I know that just over 5% of seasoncard holders didn't renew at all with a similar number deferring and new seasoncards issued represented about half of the number who cancelled. So not even all the cancelled seasoncards were offered as new tickets.
So while the club made a bit of a shambles of renewal in some cases, he'll have a seat that was cancelled, not one that was deferred. So stop talking shite and panicking someone about something you simply don't understand or have data for.
