Explain your concerns to your bank manager in writing as soon as you discover something may be wrong
Ask for a written explanation of how the figure was calculated
If you are dissatisfied with the reply, ask to speak to someone at the bank
Don't be intimidated! Remember your bank will consider its own priorities before yours. Don't be afraid to challenge your bank manager if you believe there is a mistake.
Ask your bank about its internal complaint procedures if you feel a formal complaint is necessary
If there has been no error but you think charges are too high, you may wish to consider switching to an alternative service or moving to another bank
If you suspect that errors have been made, but are unsure, the Independent Banking Advisory Service (IBAS) will investigate your accounts to establish whether a full audit is necessary. They do not charge for the initial investigation. Visit their website on www.ibas.co.uk
To help you negotiate a refund of charges with your bank you may enlist the services of a specialist banking auditor, who will charge a fee plus a percentage of any amount recovered.
