An apartment complex that I was applying to uses CoreLogic to check the credit history of potential lessees. When I applied to the building, I was told that my application had been rejected due to an issue with my credit history. I immediately contacted CoreLogic to see what the exact issue was, and was told it had to do with a debt owed to a debt collector called XXXX XXXX. When I contacted XXXX XXXX myself, they told me that they had no record of such a debt, and that they had not provided information about a debt to any credit reporting agency. I obtained a letter from XXXX XXXX stating as such, and provided that letter to CoreLogic. CoreLogic has since deleted the false information from my record, however they will not tell me where they got the false information from in the first place, other than to tell me they got it from XXXX XXXX XXXX, a company whose " Contact Us '' page on its website links directly back to CoreLogic. I want to ensure that this false information does not exist in the records of any other company, however I can not do so if I do not know which other company to contact. I am also concerned with CoreLogic 's failure to reasonably ensure that the information it receives and disseminates is correct. While I understand that mistakes are made, it concerns me that CoreLogic had information supposedly from XXXX XXXX that XXXX XXXX knew absolutely nothing about. There should be some responsibility on CoreLogic to ensure that it is getting information from a reliable source before potentially damaging a consumer 's credit history.
