I bought a Christmas ball at the Gloucester game. The money went off and has since gone back on!
When I have phoned or emailed the club before the usual response is that it will be sorted by the next match day, which, to be fair, it always has been. I am hoping this oversight is missed!
As for the rewards, the options are interesting but I am going to try to save up for something later in the season. It might be a good system in the long run but I did like the old cashback.
