Netshort Charged Me Twice and Still Did Not Activate My Subscription

I made a payment through the Netshort mobile app on June 20 via my Opay bank card for a Play Store transaction, and I was debited twice for the same operation. In total, 43,000 naira was taken from my account instead of a single charge. Despite these debits, even the first amount that was correctly taken for my subscription has still not reflected in my Netshort account or subscription, so I am both double charged and not receiving the service I paid for. I contacted Opay, and they confirmed that the transaction was successful from their side, but I still have not received any correction or refund for the extra debit, and my subscription has not been activated. At the moment, my money is with the merchant side and the issue has not been resolved. I request that the wrongly charged amount from this double debit be fully refunded or reversed back to my Opay bank card as soon as possible, and that my original subscription payment be correctly applied so that my subscription is activated, and that I be informed in writing when this has been done.
