Microsoft Outlook

My Outlook account is shown as having been suspended as the direct debit has been declined.  have checked with my bank and they say that they have not received any request for payment. The bank account information shown is still correct so I have no idea why the subscription has not been renewed. There is no facility to edit the direct debit information in any case. I have tried to mange the subsriction and change the payment method but always seem to get to a dead end. There is no live support for Outlook so I have no real alternative but to cancel my subscription.
