Sorry folks for hurried posting last night, and lack of details.
Tha final straw was when I went over my overdraft limit by by £3.50 for one day and was charged £20.
I rang the branch and got no joy. Then I wrote a formal letter of complaint to the branch and they reimbursed me with £84 as "a gesture of goodwill".
I then wrote to customer relations at head office and they endorsed the actions of my branch.
Filled in Claim form at County Court. After receiving court papers, bank filled in an admission form and sent me a cheque for the full amount claimed including interest and court fee. I really enjoyed paying this into my account. Total amount I got back was £240, a small amount but very satisfying.
