Complaint sub-issue: Their investigation did not fix an error on your report

I I have received the statement from US bank dated XX/XX/XXXX on about XX/XX/XXXX due to Covid mailing delays. The account is HELOC XXXX. The due payment date was XX/XX/XXXX, past the date I have received the mail. Min pmt was {$130.00} and balance of {$3700.00}. I have called US Bank immediately and informed that I made a payment from XXXX in the amount of {$3700.00}. Apparently XXXX  delayed the transfer of funds. But they were eventually received by US bank. On XX/XX/XXXX I have asked for the final for final pay off and removal of the late fee of {$29.00}. The fee was removed later and the rep quoted the balance of {$140.00}. I have made this payment on XX/XX/XXXX via online transfer from XXXX XXXXhecking account. I assumed that my account was completely paid off. 

To entice me to use US Bank HELOC, US bank makes me promotional offer to lock the account with fixed rate of 2.7 % for 36 mo, as long as I spend $ XXXXby XXXX XXXX. Which I did on XX/XX/XXXX On about XX/XX/XXXX I called US Bank to verify the promo rate of 2.7 %. I was told by US rep that this did not take place and my account was suspended due to the late payment of {$5.00} on {$150000.00} HELOC. As of XX/XX/XXXX I have not received any statement showing that I still had a balance on the account that I paid off on XX/XX/XXXX based on the information provided by US bank. I took care immediately over the phone of {$5.00}, conf # XXXX On XX/XX/XXXX I have received cashiers check for {$29.00} dated XX/XX/XXXX as an overpayment on the account On XX/XX/XXXX I have paid off {$2000.00} since the US Bank did not fulfill its obligations to honor promo fixed rate of 2.7 % On XX/XX/XXXX I was alerted by credit monitoring agency that have late pmt posted on my credit report from US bank. I have checked XXXX and saw that US bank reported XXXX as late payment even though I have not yet received XXXX payment yet and next payment due date was XX/XX/XXXX with min of {$5.00} due that I have paid on XX/XX/XXXX with confirmation number provided above On XX/XX/XXXX I have called US bank and opened a credit dispute case XXXX. On XX/XX/XXXX I have received in mail ( I have kept original envelopes ) 3 letters from US Bank dated XX/XX/XXXX : 1. Account summary with min payment due of XXXX by XX/XX/XXXX. I have paid this amount on XX/XX/XXXX 2. Letter dated XX/XX/XXXX informing about past due amount of {$0.00} with a threat to suspend an account if this {$0.00} is not paid by XX/XX/XXXX 3. Letter from US bank dated XX/XX/XXXX with reference code 122 stating that US bank reported {$0.00} to credit agency as late payment. I work for XXXX XXXX XXXX and we treat this amount as a rounding error during pay off. It certainly did not grant the right to US without courtesy of trying to collect {$0.00} from me I have mainted my FICO  820-850 my entire life. To be reported to burp for {$0.00} due on XX/XX/XXXX while US bank send me on XX/XX/XXXX cashiers check for {$29.00} overpayment, is simply radiculous. 
I request your assistance to remove reported late charge of {$0.00} from all 3 buros as it significantly impacted my credit score. 

I understand mistakes happen. Never less, what I have experience with US Bank, ie late fees during Covid due to delays in US mail outside of my control, bait and switch offer to entice me to spend {$2000.00} with US bank in exchange of the better rate that never materialized, and late payment reporting of {$0.00} in XXXX while the payment was due on XX/XX/XXXX and is round error of the pay off amount, is beyond any reasonable explanation and I consider these practices predatory and in violation of my consumer rights in the State of CA. I have received today result of XXXX  investigation refusing to remove the late charge from my buro and advising to resolve with US bank. They have received my case on XX/XX/XXXX via fax from the local branch with all supporting documentation. I am asking your assistance to investigate predatory lending practices and bate and switch offer of US Bank, late fee charges during Covid beyond my control and removal of late payment record for this banker from all 3 buros. You help is appreciated. I have all supporting documentation, phone records and copies of the postal envelopes that have no mailing dates and were delivered to me with significant delays. Additionally I the account was overpaid by {$29.00}, US bank could withheld {$0.00} and refund me the balance. This would avoid this entire mess. Thank you, XXXX XXXX
