On XXXX/XXXX/XXXX I received an email from Capital One regarding a decrease in my credit limit from XXXX to XXXX in which the company stated " may ''  affect my credit score. I opened the card last year to have access to a XXXX credit card since many vendors do not accept XXXX XXXX ( my primary charge card I 've had since the XXXX 's ). The reason Capital One gave was 1. low activity and 2. not high enough balances. I am a XXXX and run on average of 4 to 5 thousand dollars minimum each month through XXXX and not on my Capital One card. Also I have never been late or behind on ANY cards my entire life. When opening the Capital One card I did not ask for a XXXX credit limit. Because I pay my balance off each month no matter the amount, I never accrue interest. In addition my credit limit is higher with XXXX. XXXX XXXX does not change my limits due to inactivity and XXXX detected the decrease and as a result, lowered my credit score. Also with the other 2 credit reporting agencies as well. Upon calling Capital One and talking to 3 people to get to the executive office, XXXX ( a manager in the executive office ), told me there was nothing to do except charge more and ask for more credit. I discussed this with XXXX. I was told by the executive office at Capital One, they would not increase the limit and nobody would call me. Conversation was recorded. I asked to have this decision be reversed and told no. I asked why a decrease and let me know what I have done to warrant this. No reason other than inactivity and low balance. Low balance and decreased activity did n't affect my credit limit on other cards, and paying card balances off is fiscally sound! The conversation solved nothing and sounds to me like they want me to run a balance for them to make money and lower their Teir 1 balances. Capital One knew what they were doing and how it would lower my credit score. They did not have to lower the limit as it will still not change what I charge and keeping my balance low. I feel that the only solution is to run up high balances and ask for an increase in my credit limit is what Capital One wants. My other companies have never done this. If I need to borrow money for a car loan or mortgage company, my lower credit score WILL affect my loans. I am asking for an investigation and expect my credit score to return to it previous level. That will probably mean raising my credit limit and or expunge the damage from their letter. I did n't ask for the XXXX limit to begin with. My conversation did nothing to allow me to feel good about this company. I was told they could do nothing to help me and reiterated over and over what the decision was, not the " why '' of the decision when I have never, ever been late with paying, never carried a balance and always paid on or before the bill 's due date. I will be dropping this company when I 'm able to find another XXXX  company. I 've discussed this with my personal banker. The President and Vice President of my bank XXXX encouraged me to write to you as the activity may be legal, but knowing the drop of the credit limit will affect me for Capital One 's benefit. Also my bank President informed me that the XXXX 's credit card company would not drop their customer 's limit unless of a PROBLEM. I have a clean record. No issues. The discussion was threatening from the executive office of Capital One. Although I am angry, not having the opportunity or ability to solve the problem with Capital One makes me believe the drop was intentional to benefit them financially in Teir One balances. I will provide you the emails and letter. You may have access to all my card balances and history for this investigation. Thank you
