We offer a 48 hour grace period for all payments and should you not make your payment within 48 hours of the due date of your invoice your services will be automatically suspended. All that is needed to re-activate the service is to pay the outstanding invoice and the billing system will automatically un-suspend your account.
Should you have any questions about this or your account doesn't automatically un-suspend for any reason by all means do open a support ticket in our billing department.
