Completely off-side

<p>How can you decide to change the date of my end of December debit order in favour of yourselves to an earlier date? We have a long-standing debit order agreement for a certain date, which I authorised. I have never authorised a different date, so why must I go to the trouble and expense of sending you an sms response to confirm that i dont accept your unauthorised changed date. What part of contract law and customer focus dont you understand? Highly irritating.</p>
