Payment Problem
I have $560 in my apple wallet which is only redeemed using apple gift card that means I haven't added a credit/debit or any other payment method. Now when I try to buy ingame credits like UC in Pubg Mobile. It shows up error like "Your Purchase Could Not Be Completed. For assistance, contact iTunes Support at www.apple.com/support/itunes/ww/."
iPhone 12 Pro Max, iOS 15
