[This letter should accompany the form, which will be sent on request if you phone the Financial Ombudsman Service.]
Reference: [bank/society and account number]
I am in dispute with the above [bank/ building society] in respect of unauthorised withdrawals made from my current account.
I'm enclosing my complaint form and all the relevant correspondence, from which you will see that I have been unable to reach settlement with [bank & branch], despite having contacted its head office.
I would therefore be grateful if you would consider the case on my behalf.
