Unable To Access DramaWave Service After Paying

I am using the DramaWave – Dramas & Reels app in the United States through the Apple App Store and I have been repeatedly charged even though the app keeps requesting payment as if I had no active purchase. On 21, 24, 25 and 28 August and on 31 August and 1 September, I was charged 9.99 USD each time for DramaWave, but every time I open the app, it still asks me to pay again instead of recognizing my payments. Because of this problem I cannot properly use the service I paid for and I am concerned about being charged multiple times for the same thing. I contacted Apple support about this issue, but they directed me to reach out to you. I request that all the incorrect or duplicate DramaWave charges made through my Apple account be checked and that the total 9.99 USD already taken for this subscription be refunded, and that my account be corrected so that, if I choose to continue using the service, the app recognizes my valid purchase and does not ask for further unnecessary payments.
