Is there anyway of restoring a purchase, like refunding it?

It may be best to reach out to the official Chat/Phone Team for additional assistance:

You will need to contact Mojang, my friend. Only their support can tell you if they will be able to refund or restore it back to your account.

I don't think a refund will be given, but they might restore your purchase to your new account.

With an issue like this, you need to contact Xbox customer support. I believe they have the ability to restore your license, or at the very least refund you so you can purchase it again.

Hope this helps

i actually purchased it while it said it was on sale, not realizing that on the confirm purchase it said $29.99. Is there anyway to be refunded that overcharge?

I lost 6 movies recently after the xbox video app updated and they were purchased between late 2011 and 2013 microsoft refused to refund my movies i lost and were very rude. I restored my purchase history on the xbox one and they are still gone. I could
watch them the night before too so be careful they could just disappear anyway since you cant download them now and microsoft will not be of any help.
