Since it will be 1 January tomorrow, why not use the www.annualcreditreport.com website and get all three bureaus for free? Then, when logged in to each of the bureaus, you can easily initiate a dispute from there.
Please be sure to ONLY go to www.annualcreditreport.com (there are others that have similar names to trick you) as that is the website set up by the three bureaus for each US citizen/resident to get a free annual copy of your bureau as mandated by law.
