Product: Credit reporting or other personal consumer reports

I am submitting this formal complaint to the Consumer Financial Protection Bureau ( CFPB ) against TRANSUNION for failing to adequately address and correct an inaccurate late payment mark on my credit report. 
Account XXXX XXXX XXXX XXXX XXXXXXXX # XXXX The circumstances surrounding this delay were entirely beyond my control and were caused by procedural failures on the part of the creditor. Despite disputing this late payment with TRANSUNION and providing substantial evidence to support my claim, the bureau has failed to properly investigate and correct this inaccurate reporting. 
Details of the Complaint Erroneous Late Payment Reporting : The late payment mark reported on my credit file stems from the following situation : Prior to the payment due date, my account experienced a fraudulent transaction, which I promptly disputed with XXXX XXXX XXXX XXXX. 
The unresolved dispute led to a block on my account, preventing me from accessing it to make a timely payment. 
The payment was made on XX/XX/year>, immediately after XXXX XXXX resolved the issue. 
The delay in payment was entirely caused by XXXX XXXX failure to act promptly to address the fraudulent transaction and unblock my account. This late payment does not reflect my financial responsibility or payment behavior. 
TRANSUNIONs Failure to Investigate : Despite submitting a formal dispute to TRANSUNION with clear evidence demonstrating the inaccuracy of this late payment mark, TRANSUNION has failed to properly investigate and correct the information as required under the Fair Credit Reporting Act ( FCRA ). Instead, the inaccurate late payment remains on my credit report, causing significant damage to my credit score and financial standing.

Harm to My Financial Standing : This inaccurate late payment mark has caused unnecessary harm to my credit score, jeopardizing my ability to secure financing for my business. It is unjust for this negative mark to persist on my report due to failures by both XXXX XXXX XXXX XXXX and TRANSUNION to fulfill their legal obligations. 
Legal Violations by the Bureau Agency Failure to Conduct a Reasonable Investigation ( FCRA, Section 1681i ) : TRANSUNION is required to conduct a reasonable investigation of disputes submitted by consumers. The bureau failed to thoroughly investigate my claim, disregarding the evidence I provided that clearly demonstrated the inaccuracy of the late payment. 
Failure to Ensure Maximum Possible Accuracy ( FCRA, Section 607 ( b ) ) : TRANSUNION has a legal obligation to ensure that all information on a consumers credit report is accurate. By failing to address this dispute, the bureau is perpetuating inaccurate information on my credit file.

Negligence in Verifying Information Provided by the Creditor ( FCRA, Section 1681s-2 ( b ) ) : TRANSUNION is obligated to verify the accuracy of the information furnished by XXXX XXXX XXXX XXXX XXXX This obligation includes ensuring that any negative marks reported are accurate and substantiated. 
Violation of My Consumer Rights : By failing to correct this inaccuracy, TRANSUNION is violating my rights under the FCRA, causing undue harm to my financial reputation. 
The inaccurate late payment mark on my credit report is unjust, harmful, and violates my rights under the FCRA. I urge the CFPB to investigate TRANSUNIONs handling of my dispute and ensure that this matter is resolved promptly and fairly. 
Thank you for your attention to this matter. I look forward to a resolution that reflects the fairness and accuracy required by law.
