Unfortunately, if you are seeking a refund you'll need to contact Apple's/Google's/Amazon's Customer Support directly.
They handle all of our in-app payments, and as such, any and all monetary reimbursement will need to come directly from them. If you are unable to work out an amicable solution with them regarding the refund, or if you do not wish to pursue a refund, please let us know. We would be happy to send you the purchase in question.
If the provided resolution does not address your concern, please contact our Support Team at https://smurfsmagicmatch.zendesk.com/hc/en-us.
