Hi Misspinkpanther
You can claim back the interest at the rate of 8% on each charge, but this can only be done at the court stage of the process. If you want to claim back Contractual Compounded Interest at your APR rate, that is what they have charged you on each penalty, then you have to ask for this at the start.
You can claim back the Overlimit fees and Late payment charges. You need to list them in a spreadsheet. If your not asking for APR then just list the charges, date, amount, reason, and days passed, then ask for them back.
To work out your APR, on your monthly statement you should have below the transaction box, your current Purchase interest and cash advance interest. It will be some thing like:
Purchase Interest 1.897%
Cash Interest 1.976%
Add these 2 figures together to get an average and divide by 2, then type it into this calculator found here:
http://www.shweb.pwp.blueyonder. co...Sheet_v1.9.xls Do not use the spreadsheet on here, as it's for bank charges only. The calculator is very accurate. If you don't have your APR or % figures, call them asking what it currently is.
When you have your APR, type this into your spreadsheet on each charge. It is not uncommen for people to have an APR of 34%...
Hope this helps
