Tony,
Looks like standard info from a creditor. You obviously are not after a "notice of correction" on your file but updates/deletions to it.
Guidance on how to complain is on the ICO website along with a complaint form.
http://www.ico.gov.uk/complaints/data_protection.aspx
In terms of legislation you could quote the Data Protection Act, several "Principles" apply in that personal data should be accurate and kept up to date, not kept longer than necessary for a specific purpose and processed with the rights of the Data Subject (That will be you) come to mind
There is also a guidance note on defaults
http://www.ico.gov.uk/~/media/documents ... 20DOC.ashx para 47 which states your rights to get inaccurate default dates amended to the date of your IVA.
HTH
PS: Also if they have given you a "final decision" and its been 8 weeks you can also get the Financial Ombudsman on board.
We're willing to wipe the slate clean, give you a fresh start. All that we're asking in return is your cooperation.
