Thanks for your post and apologies to hear you've been having an issue since moving address.
When you move, a new account is set up with a new account number. We would need to complete a move and transfer to allow your new account to be attached to your old details. We can arrange that for you here.
To do this, I will need to clarify a few details with you. I have sent you a private message regarding this. Just click on the little plum envelope at the top right hand side of the page to access your inbox.
