Hi Emsiejayne,
Thanks for your post and apologies to see that you are having trouble updating your direct debit details and the help given already has not sorted things for you.
Depending on the account status, the option to change the Direct Debit may not be available. I can check this for you however will need to confirm some information with you. I have sent you a private message regarding this and will investigate further once I receive your reply. Just click on the little plum envelope at the top right hand side of the page to access your inbox.
Thanks,
