Product: Credit card

Dear Citi Bank Customer Service, I am writing to express my serious concerns and to file a formal complaint regarding the recent and abrupt decrease in my credit card spending limits, which has resulted in an over-limit balance that I am now being asked to pay. My name is XXXX XXXX XXXX, and I am the holder of XXXX credit card accounts with your institution, numbered [ Credit Card Number XXXX ending in- XXXX ] and [ Credit Card Number XXXX ending in- XXXX ]. In early XX/XX/XXXX, I made substantial payments to both accountsone payment of {$5000.00} ( XXXX ) and another of {$3500.00} ( XXXX ) demonstrating my financial responsibility and commitment to maintaining a healthy credit standing. Despite these significant payments, I was shocked to discover that the spending limits on both cards were reduced without any prior notification, effectively absorbing the large payments I had made and leaving me with an over-limit balance. I am also expected this month to make a {$4300.00} monthly XXXX payment to account ending in XXXX for the over-limit balance. I had to make a payment a over-the-limit payment of {$1400.00} to account ending in XXXX. Both Citi Bank XXXX credit card/over-the-limit payment total {$4800.00}, which would be financially unbearable. I have consistently demonstrated my reliability as a customer, having never been late with a payment for either card. It is my belief that this reduction in my credit limits XXXX have been unjustly influenced by a dispute filed with XXXX XXXX Mortgage, which should not have any bearing on my standing with Citi Bank. XXXX XXXX Mortgage submitted my personal financial information that violated consumer protection laws. Moreover, I have made several attempts to contact your customer service department to obtain clarity and information regarding this matter, but my requests have gone unanswered. This lack of communication is not only frustrating but also unprofessional, and it does not align with the level of service I expect from a reputable financial institution. I would like to bring to your attention that, according to the Consumer Financial Protection Bureau, credit card issuers are required to provide a XXXX notice before charging over-limit fees or applying penalty rates due to a decrease in the credit limit. Additionally, the Equal Credit Opportunity Act mandates that credit decisions should not be influenced by discriminatory factors. Given these points, I request an immediate and thorough investigation into the reduction of my credit limits and the subsequent over-limit balance. I also demand that my credit limits be reinstated to their previous amounts and that any over-limit fees incurred due to this reduction be waived. In addition, I will also be submitting my complaint to FDIC XXXX XXXX, Consumer Financial Protection Bureau and XXXX XXXX XXXX ( Equal Credit Opportunity Act ). I trust that Citi Bank will address this issue promptly and fairly. I expect a prompt response to this letter, including a detailed explanation for the decrease in my credit limits, the steps taken to ensure compliance with federal regulations, and the actions you will take to rectify this situation. Thank you for your attention to this urgent matter. I trust that Citi Bank will take the necessary steps to resolve this issue in a fair and timely manner. Sincerely, XXXX XXXX XXXX
