There is nobody to report them to. You would have to dispute the debt and request proof of it. If they fail to produce it, they are supposed to take it off your credit report. However, that doesn't always happen. Credit reporting is one of the biggest frauds out there. There is a lot of fabrication - from personal experience, I know. Mine is and was riddled with fabrications. One such - I was supposedly bankrupt when I was 11. ELEVEN! And I had never set foot in this country at that time, and accounts I never opened and had no knowledge of - one was being paid on regularly. If they won't fix it, you would have to hire a lawyer to get it fixed. It is costly and could take 3 or 4 years. I never bothered about mine. I never intended to borrow money - never needed it. Years later, house purchase - I did need a loan. I got it. No problem. Just tell the lender that your credit report is full of crap. They will check it out - you may or may not qualify but, if you have no knowledge about it and they can verify it, don't worry about it. Still, you ought to dispute it.
