I have contacted the credit reporting agency Experian multiple times regarding negative items ( XXXX and XXXX XXXX ) on my credit report that I believe is not mine. I told them I tried to contact the collection agencies directly to acquire a billing statement showing proof that the debt belongs to me but the phone number on the credit report is not a valid phone number. I asked Experian how are they getting in touch with the collection agencies to continue to report negative items on my credit report and I also ask for the credit bureau to provide proof of the information the was provided to them from the collection agencies. Experian stated that they have not receive any information from the collection agencies to instruct them to remove the negative reporting, but my question to them was how are they validating that the information is truly for me. If the collection agencies have not responded to Experian, why Experian continues to report negatives items that I have disputed and I believe is not valid. I also ask Experian to provide proof that they validated the information with the collection and to provide the phone number, email, or address that was used to validate the debt. Experian told me they were not able to provide that information to me and I should use the number on the credit report that is not valid. Why I ca n't get proof or speak to someone concerning the validity of the debt??? I believe the continuous reporting is un-just because I have not received a billing statement or proof related to the debt from the collection agencies or received proof from the Experian showing how they were able to validate the negative items.
