I was sad to find that there is no option to have only a portion of the money I've spent on Glitch refunded rather than all or none.
Glitch was a wonderful game that I enjoyed playing for over a year. I think they deserve to keep a good portion of that money for all their hard work despite how broke I am. On the other hand a big part of the reason I paid for the subscriptions was in order to buy virtual items that are now evaporating so I think it's fair to get some of it back.
Long story made short, I wish there was a way to opt for a partial refund!
