Product: Credit card or prepaid card

I received a notification on XX/XX/XXXX that my credit score had dropped XXXX points from XXXX to XXXX and when i logged in to see what changed I discovered that Target/TD Bank XXXX XXXX missed payment on my credit report of {$35.00} missed from XXXX. I have NEVER missed a payment on that account or any other account which can be seen on my credit report. 
I then called Target/TD Bank ( on a recorded line ) and let them know I not only never received notice of a missed or late payment but never received a call about a delinquent payment. I also was signed up for auto pay of which the customer service representative claimed I never was signed up. I then asked " why did no-one contact me? '' to which the customer service rep responded first they do not have to and some people they do not contact and then changed her statement saying I have a do not contact listed on my account. 

I let her know I never discontinued auto pay and I have never authorized a do not call/contact and asked for a supervisor of which she refused stating they could not assist me or fix this reporting error, but finally put me through to a supervisor who repeated the same thing and said she would put a request for dispute but no-one ever contacted me and the dispute was not handled. At this time Target/TD Bank drops my my credit limit from {$15000.00} to {$1500.00} further tanking my credit score and making my Target/TD Bank card account balance of {$1400.00} almost maxing the account, which is not only punitive, predatory but deceptive lending practices. This action then affected my credit limit of another card which is/was in good standing with a {$6000.00} limit decrease and create the same punitive action, all because they did not call or notify me that a payment was late within 30 days of them stating they never received XXXX payment of {$35.00}. 

At this time the punitive action caused by Target/TD Banks deceptive practices and fraudulent reporting has cost me {$2000.00} because I have had to pay down XXXX and Target/TD Banks card to prevent further damage to my credit. 
I received the XXXX dispute report stating they will not have Target/TD Bank change or remove this and the 30 day late payment will remain on my credit report EVEN after I paid {$190.00} on the phone with them XX/XX/XXXX to cover the {$35.00} late payment and another {$600.00} on XX/XX/XXXX because they dropped my credit limit almost maxing my card out. 
These punitive actions should never have occurred, would have been immediately remedied had they called me about the late payment, again I have NEVER missed a payment, especially for {$35.00}. 
So moving forward to today, they fraudulently reported on my credit report not only the 30 day late payment which will affect my credit till XXXX but they fraudulently reported the late payment incorrectly as XX/XX/2023 instead of XXXX which is when the apparent missed payment occurred because somehow the autopay was removed from my account and a no call/contact was added but they can not tell me when or why, ..they just say they have no record of the autopay ever being on my account and no record of who authorized a no call/contact on the account. 
The actions of Target/TD Bank the XXXX issuer to not inform are deceptive, lowering credit limit to max out a persons account is punitive and adds high interest and burden to the card holder in the form % of used credit and affecting consumers overall credit rating/standing with all open accts or lenders but the fact that they also fraudulently report to the credit bureaus the inaccurate month the apparent transaction occurred is warrants a closer look at their deceptive practices and unfair treatment of long-term customer/consumers by both Target and TD Bank. 
I have been a customer and card holder member for almost a decade or more and never missed a payment and even pay extra every month ahead of my payment due date. 
At the very least I would like to have this fraudulent reporting removed from my credit report and at the most Target/TD Bank should be fined or shutdown for fraudulent, punitive and deceptive practices burdening consumers. 
My payments are due on the XXXX of every month, WHY in 30 days did they not reach out to me at all? WHY did they wait till XX/XX/XXXX to report this without contact even though I paid {$190.00} on XX/XX/XXXX and {$600.00} more on XX/XX/XXXX and why drop a consumers credit limit to almost maxxing the consumer account limit for {$35.00} late payment? These deceptive practices are the reason for the Consumer Agency Protection Bureau and I pray something is done since the credit bureaus will not assist. 
Please assist me in resolving this so that other consumers do not have to be deceived by Target/TD Bank ever . 
Thank You!
