Thanks, sorry I didn't mean to hijack.
So for the letter, does this sound right?..
To whomever it may concern,
I have recently discovered that you have placed a default on my credit file (attach screenshots of default) with Experian, Equifax and Call Credit. I believe this to be in error as I have had no dealings or communication with Motormile Finance, nor any other credit provider from whom you may have obtained data where a default notice has been issued. Given these entries are inaccurate and unlawful, I must request that they are removed in their entirety within 14 days of this letter. Failure to do so will result in a complaint being submitted to the Information Commissioner's Office in addition to my seeking compensation through legal action.
Kind regards,
B
