Complaint sub-issue: Was not notified of investigation status or results

To Whom It May Concern, Please be advised that I have received your computer-generated 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. 
You were advised by me on XX/XX/2022 by certified mail that I questioned the accuracy of a few items on my credit reports. That request was written by me and mailed by me- not a third-party agency. It appears obvious to me that you are abusing your power under the FCRA to escape a complete investigation. 
Here again is the incorrect information being reported : 1. FDCPA 807 False misleading information FDCPA 8012 furnishing deceptive forms. This agent is in violation of 15 USC 1692g Because they were to notify me of this in writing 5 days prior I was not. As the original creditor only I can validate this debt. 
XXXX XXXX  XXXX : XXXX This account is inaccurate and fraudulent. Im seeking Litigation. Please delete at once. 

2. THIS COMPANY IS IN VIOLATION OF 15 USC 1681N THESE ACCOUNTS MUST BE REMOVED IN 4 DAYS 15 USC 1681C-2 these accounts are not mine. 
XXXX XXXX Account XXXX : XXXX This account is inaccurate and fraudulent. Im seeking Litigation. Please delete at once.

Additionally, there is NO law that states a consumer can not use a third party, so using that as your excuse is a irrelevant. In fact, the United States Congress has found the whole process so overwhelming that they afford consumers the right to use a third party on their behalf if the consumer so chooses. This is why your statement is so shameful. 
I reserve the right to sue a credit bureau for violations of the Fair Credit Reporting Act and I believe I can prove that you did not use reasonable measures to insure the accuracy of my credit reports and now you are stalling the process even further. 
I realize disputes can be expensive and it is your job to stall them, but you do so at great risk. Please take notice that this letter dated XX/XX/2022 is formal notice to you that I am requesting that you continue forward with my original investigation request and please send the results to me within 15 days. I therefore legally and lawfully refuse your " form letter '' thus giving you only 15 days not 30 more. 
I am annoyed and outraged at your accusation and I have researched my rights in regards to my credit file. Please expedite my original request immediately.
