Sorry to hear about that.
I didn't receive any notification or money from your purchase(s), so I don't think the purchase( was completed.
What you're experiencing sounds very similar to what was described in this thread:

Please have a look in that thread. According to leafo (itch.io admin), there might be a temporary charge taken from you even when purchases are not completed. But the amount should be returned to you within the next day.
Like it's mentioned on that thread, you can also contact customer support for more informations.
I hope everything gets fixed soon!
