Once a payment to Guesty has failed, Guesty gives a seven-day grace period before your account is deactivated. During those seven days, a reminder email will be sent every day to the account's admin user reminding you to update the account's credit card details. After seven days, the account will be deactivated.
Once the payment has failed, listings that are not yet activated cannot be activated. You can activate listings only after a successful payment has been made.
