Danny...
I got my letters from the
WHICH web-site, there's a link on the right of the main homepage.
Just got all my statements from the last six years and totalled all the charges. If you don't have your statements you can request them for a nominal fee of about £10.
Then
WHICH site recommends writing an initial letter asking for the charges back, then if you don't hear anything then they have a "stronger" second letter to send.
I hand delivered mine to the bank last Friday morning and had a letter today saying the complaint will be actioned before 14th May. Not bad for about an hours work.
