Website

I've been trying to change my debit order date for over a week now, called the call center and I was transferred to "customer service" were I was on the IVR for over 30mins listening to the horrible song and the woman's voice telling me about the self help service on the website. I took time and registered got an option to update my debit order and to my surprise I couldn't not due to an error saying that I have no banking details registered but they debit my account every month.
