You can also complain direct to the credit referencing agency and ask them to remove the incorrect information. Get a report from all three referencing bureaus (Experian, Equifax and Call Credit) as they might not all hold incorrect data as some companies only report to certain agencies. They have an online complaints and corrections form on each of their sites. give them a reasonable length of time to investigate and be ready to provide them with proof of your side of events and then take it from there. If they don't amend it then you can approach the Ombudsman.
