How To deactivate a Banned PSN Account
Once PSN bans your account, you cannot deactivate it. Therefore, you will get prevented from using your account until the ban gets lifted if it is a temporary ban. If your account is permanently banned, your chances of getting it back are close to zero.
But instead of giving up, you can contact the support team, write a long letter explaining the situation, and promise never to repeat the mistake. However, this is not a guarantee that the support team will lift the ban because, in many cases, the decision to suspend your account is final. If you are lucky, the support team may help you gain access to your account.
When PSN suspends your account, you will know when trying to access it. When you attempt to log into the PS console or account, you will get an error code. Moreover, in most cases, they send suspended users an email explaining the reason for the suspension and the period it will last. If you have not received the email, you can check the spam messages of the email connected to the account. Please contact customer support if you think your account is suspended but have not received a notification.
Before PSN suspends your account, the safety staff does a thorough investigation. Because an investigation gets done before an account gets suspended, their decision is final and cannot get appealed. The only case PSN allows you to appeal is when the account was suspended due to debt. If it is a debt, they will enable you to pay, and your account suspension gets lifted after the payment. Additionally, during a permanent suspension, you may appeal.
When your account gets suspended, some settings for canceling subscriptions and adding or removing payment methods are deactivated. However, that should not worry you because PSN will not take your payment for any subscription when the account gets suspended. You need to contact the support team if you must make changes to your subscription when you get suspended.
Unfortunately, there is no way users can deactivate a banned account. Once you are banned, all your account settings are deactivated, meaning you can barely do anything from the account. If it is a temporary ban, you must wait until it gets lifted. Moreover, if it is a permanent ban, the chances of deactivating it are minimal, but you can try sending a message to support and explain your issue.
