Debit Order Woes

<p>I changed banks in July and what I thought would be an easy process, changing my debit order details for my three private data accounts, has been a seemingly impossible task. The first month it worked fine, then for some reason for the past three months the debit order transaction has failed. Every month I go to Vodaworld and they assure me its fine - last month I even got a screen print as proof. But alas it has failed third month in a row. To add insult to the injury of having my accounts suspended, I also get charged for a failed debit order! How difficult can this be? </p>
