I am claiming unlawful charges against Barclays on behalf of my partner. I have kept a record of all communications between them and us. After they had sent copies of her bank statements for the past 6 years, I reckoned that they had charged her £1233 in unauthorised charges over this time. On 1st August, I wrote to Barclays informing them of the calculated charges (using templates from this forum). At no time did they ever attempt to give any reason for the charges applied to the account even though I had invited them to do so as well as supplying them with copies of the statements containing the said charges.
Barclays responded on 30 August with an offer of £380 in
full and final settlement. This was refused; Court action was begun and they supplied a defence. We have submitted the
Allocation Questionnaire. I have used the spreadsheets supplied to calculate
interest for each charge. However, I had included deductions for 'Account Fee' on my initial claim and also included these in the Court papers. So, rather than £1233, the claim should be for £895.17. Should I inform the Court of my error? Maybe that's why Barclays said nothing....to succeed through my failure?

Any advice would be appreciated. Thank you
