During an evaluation of my credit report, I noticed a company by the name of XXXX billing which is in California. I contacted the company to find out what type of business they were and the rep told me they finance auto and home. She attempted to look me up in their system by using the last XXXX digits in my SSN and my last name. She could not locate me and I asked her why were they on my credit report and she said she did n't know but it could be a case of identity theft. She told me to contact XXXX and let them know. They would contact XXXX billing and XXXX billing would tell them I am not in their system. I did that. Now I 've received a letter from Equifax stating that XXXX billing is not reporting on the Equifax credit file. That is not my XXXX dispute and I made it clear to them. My dispute is why is this company on my credit file and I 've never done business with them?? I 've never heard of them. I want them off of my XXXX credit!!! I 'm sick of this!
