I ran into the same issue. I enrolled and got the subscription on Apple Developer app on iPhone. But after payment, the app shows account cannot be enrolled via mobile app and ask to enroll via web. I did, and I got charged again. How do I refund the subscription from app store? https://reportaproblem.apple.com/ doesn't let me refund and says I have no products eligible for refunds. Who/where do I contact to refund apple developer program double charge?
