I think the points stay there for a bit but you can't use them, as there is no stage for members with X number of loyalty points, and I'm fairly certain you don't gain them for buying tickets as a member. Probably just a grace period sort of thing in case you cancel then get a new season ticket in a short space of time, as if anyone is doing that, then they get wiped. I fully expect that's my 49 gone since I cancelled.
