Mobile Legends Top Up Paid but Balance Not Received

I purchased a Mobile Legends top up from Kupikod using my card one day ago, but the balance has still not been added to my game account. The payment was successfully taken from my card, yet there has been no reflection of the purchased balance in Mobile Legends. After realizing this, I contacted Kupikod customer service to report the missing balance, but I did not receive any response. I find it unacceptable that the payment was taken but the service was not provided and my messages have been ignored. I request that my missing Mobile Legends balance be added to my account without any further delay, or that my payment be fully refunded if the top up cannot be completed.
