Can I get points back from my guild?

My partner and I recently started playing PoE together. We saw that we could get a shared inventory through a guild, so we made one together just for the two of us.
Today I purchased my first points with the intention of using them on guild stash tabs, and the (incorrect) assumption that those cost the same as normal ones because they do the same thing.
I calculated the points we would need for all the basic tabs we wanted, and transferred the currency. I was then slapped in the face with the knowledge that guild tabs cost more.
With this new information I'd rather just one of us purchased tabs and we traded items between us, as the cost difference is not insignificant. Seemingly because I am the guild leader I didn't have to approve for my points to be given to the guild, so now I'm just out 455 points and in a bad mood.
Is it possible to get my points back from the guild?
