Charged for a Template I did not receive.

I purchased the Kleo dark template, and was charged for it, but when it returned to the UNA.IO market it said that the transaction verification failed, and I did not receive my item, but my money was taken. Please resolve. There are actually 2 charges, because I wasn't sure of what happened the first time so I did it again, and did not notice until later that I was charged twice. I attempted to communicate my issue with multiple members of UNA, including the developer of the Template, but no one has responded. I chose this platform because I read your 'About Us' page, and figured you would be available to help resolve issues, but it's been nearly 2 days and I have heard nothing from any one.
