I have been dealing with Experian on numerous false items on my credit report and they are refusing to complete the investigation according to the information I have given them. Each time I give them the information they ask for, I get a form letter saying " Frivolous dispute '' we will not complete, which is false. I have numerous items from XXXX on my report that are XXXX reporting as late accounts, which is false, and as public judgement s, which is also false. I contacted the Court and they told me these records are not being validated properly yet each time I get a letter from Experian, they say the investigation has resulted in the items being mine. Case in point is the name of the co-signer listed on these records. The person does not exist and the social security number does not match the name of the person listed, therefore making these records ALL false and they all should be deleted. Yet, each time I bring this to the attention of Experian, I get a form letter saying they are under NO obligation to investigate because they already did an investigation. This is complete nonsense, as they are clearly using a computer driven data drive to match only my name and information listed with a record of another person and they never investigate the co-signer information, as I told them it would clearly show these are false.
