If your recurring payment has not been charged yet and your subscription has not been renewed, there could be a few things to remember.
Firstly, if you have paid using a credit card or via an app store, wait a few days instead of buying a subscription in case the payment is late. Sometimes, payment systems are late in automatic payments, which results in a gap when your account is inactive. You can always contact our support, and they will add a free day to your account. Additionally, double-check if your payment method is not out of date. If the subscription expires, it may be worth trying to update your payment method.
Moreover, not all payment providers support recurring charges. You can visit our guide on what payment methods does NordVPN accept to know more.
