Capital One Credit Card Complaint

Capital One Credit card department,

Credit line increase/decrease New Jersey

Capital One keeps denying me for a Credit Line Increase for a credit card i have had with them for several years. The reason behind it according to them is " We were unable to obtain your most recent monthly payment data from credit reporting agency '' I decided to check with the - credit reporting agencies and all - are reporting with no issues. I have never missed a payment with Capital One and my balance is less than $500.00 on a $2000.00 limit. I keep getting offers to open a new card with them on the mail but somehow they insist they can not get access to my payment data when I applied for a credit limit increase. I search online and it appears this is a game Capital One is playing with several customers to basically force them to open new credit accounts.
