Product: Credit card

Bank of America ( BOA ) has not returned the status of my credit card account. This account remains closed by grantor and the rebuttal letter makes false statements re : my credit history. 
Background : I have been a loyal customer since XX/XX/XXXX and have NEVER been late on making any payment to this Bank of America card [ applies to all my credit lines ]. 
In XXXX XXXX, I obtained the pay off balance from the credit card representative I paid off the credit card balance of {$2400.00} on XXXX/XXXX/XXXX, again, the payoff balance /amount was relayed to me by the credit card company representative. 
Without notifying me, the credit Card company assessed additional fees of {$10.00} AFTER I paid off the entire card. Moreover, I was NOT notified until XXXX XXXX via email that the card still had an outstanding balance of {$11.00} which now resulted in the card being closed as well as reported to the credit agency by the creditor and a decrease in my credit score. 
I am currently working with credit card company to have this falsely reported error removed from my account and credit report as well as to re-open my credit line. 
Additionally, due to the decrease in my credit score stemming from this error by the credit card issuer, other creditors are revising my credit lines downward in response. 
Complaint : The BOA letter provided XXXX XXXX, XXXX is not acceptable response. While I appreciate the efforts of BOA in removing the error of reporting a delinquency from my credit report however, to still have my credit card reported by BOA as closed by the grantor/BOA due to " based on our review, we were unable to approve the request to reopen due to a pattern of late payments on accounts with other creditors '' which is an obviously incorrect and harmful statement which must be corrected by BOA as it continues to impact my credit negatively through no fault of my own. 
The reason provided by Bank of America on XXXX XXXX, XXXX regarding declining to reopen the account, was not correct, accurate nor valid. Per the BOA response provided : " Additionally, we have reconsidered your request to reopen the account. However, based on our review, we were unable to approve the request to reopen due to a pattern of late payments on accounts with other creditors and there are too many accounts with balances. A letter was mailed informing you of our decision on XXXX XXXX, XXXX. '' I am attaching my credit report to ACCURATELY document that I have ALWAYS made ALL of my payments on time without delinquency, late payments or missed payments throughout my entire credit reporting history for ALL creditors throughout my payment history. There are NO delinquencies documented on any of my credit reports as incorrectly and erroneously stated by BOA. See attached documents. 
In response that there are too many accounts with balances, the reasoning for this is due to opening my own company and currently in the process of expansion. I am attaching my most recent pay stub as documentation of my salary of ~ $ XXXX+ annually. My company is also expanding and now classified by our US Government as a Small Business eligible for Government contracts and Grants since my company of XXXX employees continues to grow. 
I request again that this credit card account be 'returned to the impeccable status ' it had prior to the misleading and false/defamatory statement of, " due to a pattern of late payments on accounts with other creditors " and the incorrect pay off amount information provided by the Bank of America representative that created this entire situation ( as my entire credit card was paid in full with the payoff amount provided by BOA XXXX XXXX ). 'Returned to status ' is defined as an open credit account with a credit limit of {$5700.00} demonstrating my credit worthiness with Bank of America XXXX
