Apple付钱不退款

Question

我们在App Store中有app。当用户付款时，付款成功但钱不从信用卡中提取。有什么问题？也许我们需要添加银行信息或类似的东西？

if PKPaymentAuthorizationViewController.canMakePayments(usingNetworks: supportedPaymentNetworks) {
             let request = PKPaymentRequest(
             request.merchantIdentifier = "merchant.com.my_app_identifier"
             request.merchantCapabilities = .capability3DS
             request.countryCode = "RU"
             request.currencyCode = "RUR"

             request.supportedNetworks = supportedPaymentNetworks
             request.paymentSummaryItems = [PKPaymentSummaryItem(label: egrn.name, amount: NSDecimalNumber(value: price))]

             let applePayController = PKPaymentAuthorizationViewController(paymentRequest: request)!
             applePayController.delegate = delegate
             self.present(applePayController, animated: true, completion: nil)
    }
