Any outstanding invoices will not be paid automatically with your new mandate. The ongoing ones are immediately cancelled on activating the new mandate. The new mandate is only applicable from your next invoice. You had better check your bank account to see if the outstanding invoice amount has been deducted. If not, you had better pay this invoice via your bank online.
