Annemarief8,
The report that you see is very different from the report that a financial institution sees in relation to you when they access a person's ICB record. The Institution will be able to see general patterns, and discern the general nature of your borrowings and repayments (or lack thereof, if this is the case). A general footprint will be left by other institutions that access your record. They should not be able to discern the name of an individual financial institution, as your personal report can.
If you log on to the ICB's website you will get a list of ICB subscribers.
If you feel that there is material on your ICB record, you should contact the offending institution verbally, initially, and back up your request in writing. Keep a copy of your letter. Give them an acceptable time to investigate your complaint. If you are unhappy with your treatment, formalise your complaint through their complaints procedure. If your are unhappy with the outcome, telephone the Data Protection Commissioner, and that Office will help you.
Your credit record is important.
Look after it.
