Equifax wrongly changed my last name on my credit report, and deleted all of my previous credit history, and started a new credit report. After several attempts of explaining the situation, XXXX supervisor found my old report and promised to combine with the new XXXX. They had XXXX credit reports for me with the SAME ssn. I initiated a dispute to have this corrected, they only updated my last name to the correct XXXX. ALL of my previous credit history is gone. I have been denied credit due to Equifax reporting my credit history incorrectly. It shows that I only have XXXX months of credit history, and I am XXXX years old with a mortgage, car loans, credit cards, etc. All of this showed on my credit report as recently as XXXX 2014. None of it shows now, and it is all current information.
