Product: Credit reporting or other personal consumer reports

I am concerned about the validity and accuracy of your recent investigation of these accounts that are reporting on my credit report. 
Last month I requested an investigation because I felt the item was not being reported legally. Couple of days ago I received a letter stating that you have ceased investigation of my credit reports because, in your opinion, you believe that I have used a third-party credit repair agency. Not only do I believe this to be a stall tactic on your part to grant you an additional 30 days to comply with my original request, but I believe it to be a blatant violation of the FCRA. 
I have attached a copy of my government issued ID as well as mail showing proof of address. So, there shouldnt be no confusion or stall tactics on your end. I have maintained a careful record of my communications with you for the purpose of filing a complaint with the FTC should you continue in your non-compliance. 
I request this under 15 U.S. Code 1692g - Validation of debts. If information is not provided or the false reporting isnt removed ; as in Wenger v. Trans Union Corp., No. 95-6445 ( C.D.Cal. XXXX XXXX ), you may be liable for your willful non-compliance. Credit reporting laws ensure that bureaus report only 100 % accurate credit information. Every step must be taken to assure the information reported is completely accurate and correct. The following information therefore needs to be reinvestigated. 
1.Please explain to me what your representatives uncovered to lead them to believe that you are reporting this item as it legally should be reported?

2.What certified documents were reviewed to conclude your investigation?
