I currently have a billing dispute regarding my XXXX credit card ending in account number XXXX. While the dispute is under investigation, the bank reported my account negatively to the credit reporting agencies. Can it do this? No. Generally, if you have filed a proper billing error dispute, the bank shall not make ( or threaten to make ) an adverse report to any person about your credit standing. The bank also should not report that an amount or account is delinquent because you failed to pay the disputed amount -- or related finance or other charges -- while the investigation proceeds. Banks are required to have reasonable procedures in place to make sure that periodic statements are mailed or delivered at least 21 days before any grace period ends. Further, for credit card accounts only, banks are similarly required to have reasonable procedure in place to make sure that periodic statements are mailed or delivered at least 21 days before the payment due date shown on the statement. The problem here is I never received a statement from XXXX to make a payment on time and therefore they placed a 30 day late on my credit reports which when disputed should not be allowed, see below. 

A credit card issuer may not treat a required minimum payment as late for any purpose if the minimum payment is received by the card issuer within 21 days after mailing or delivering the credit card statement disclosing the due date for that payment. This means that, if your minimum payment is received by the card issuer within 21 days after the statement is mailed or delivered, the card issuer can not increase the APR as a penalty, report you as delinquent to a credit reporting agency, assess a late fee, terminate benefits ( such as rewards on purchases ), or initiate collection activities.
