Consumer Financial Protection Bureau XX/XX/2021 Ref : XXXX XXXX Citibank Credit Card No Ending : XXXX XXXX Complained Ref No : XXXX RE. : Complaint against Citibank Credit Card and XXXX Hello, During XXXX of 2021, my credit score plunged XXXX points in response to Citibank reported over the credit line transaction that was unexpected and unannounced interest charge by the bank on my account. I communicated the matter with Citibank customer support who gladly forward to me a letter notifying me that Citibank had requested the credit agencies to remove over the credit line from my credit report, see copy attached. Apparently, up to todays date this matter is not resolved and still being swung back and forth for over three months now, and no clear idea is given by either Citibank nor XXXX, to investigate the matter and restore my credit score, regardless how many times or requests I had to place with them. 

The sequential of the dates related to this matter was as follows : On XX/XX/2021 I paid {$2200.00}, the total balance of my Citi credit card, so I had XXXX balance. 
On XX/XX/2021 I received an offer from Citi via mail to transfer other credit cards debts to Citi card for 0 % or 0.99 % interest rate. 
On XX/XX/2021 I called Citi and processed the offer and according to Citi representative the maximum I could get was {$6900.00} since {$340.00} were reserved for the balance transfer fee. Total of both were {$7200.00} which is equivalent to my credit limit, {$7300.00}. 
On XX/XX/XXXX, unexpectedly, my account was charged {$21.00} + {$0.00} as interest rate. This charge put my credit line above the credit limit, and hence automatic reporting of the transaction occurred and it was reported to the credit reporting agency XXXX. I knew of the transaction at a later date when I was alarmed by the sudden plunge in my credit score, which was a drop of XXXX points at once. 
On XX/XX/2021 as I became aware of the problem, I contacted Citi bank to rectify the problem. Over the course of many calls, I received a letter from Citi bank dated XX/XX/2021, copy attached. In this letter Citi Bank notified me that a request was sent to the three credit agencies to remove the over credit line comment from my credit report. In the same letter I was asked to allow 30 days to process such request. 
On XX/XX/2021 after seeing no correction was made, I filed a dispute with XXXX on the matter and faxed them Citi Bank letter dated XX/XX/2021. 
On XX/XX/2021 I saw no correction made to my credit score so I contacted XXXX to check on my dispute status. I was informed that Citibank had responded on XX/XX/2021, and denied my dispute as the transaction was accurate. 

Here is the bottom line : my dispute is not about the accuracy of the transaction, rather is about the timing and circumstances that let to such transaction to occur. It was solely based on the mis-information I received from Citi Bank representative while processing the offer to transfer other credit cards balance to Citi Credit card . The Interest charge on my account came as unexpected and unplanned, contradicting very good faith invested in the matter. Furthermore, Citi Bank had acknowledged and honored to rectify such reporting as shown in the attached letter. However, the problem is not solved yet regardless how much contacts or appeals I had filed with them to reverse the damages on my credit score. 

Please help me to resolve this matter.
