A payment can fail for various reasons: your payment details may be incorrect, your credit card may have expired or the payment might have been declined by the bank due to insufficient funds or other internal issues.
If your payment failed, please check if your billing information on App Radar is current and accurate. If you are still facing problems, please contact your bank to check you have enough funds on your card and that there are no other restrictions on your account.
Also check if you are using our accepted payment methods.
