On XX/XX/XXXX I submitted a request for a credit limit increase on my Discover credit card account both online and with a Discover agent. 
I knew that my credit score was more than 750 and that I have had no problems with any accounts, at all, for more than ten years. 
My Discover credit card account has been open for years with no problems and my present limit is {$5500.00}. 
Both of my requests were denied. 
I inquired, from the agent, as to the reason that my request was denied and they stated that the denial was based on a matter from XXXX when I included my Discover Credit Card account in my Chapter XXXX Bankruptcy, which was fully discharged in XXXX. 
I received a letter from Discover Credit Operations Team, dated XX/XX/XXXX, that stated the following, " Unfortunately, at this time we are not able to approve your request for a credit line increase due to the following : STATUS OF EXISTING / PRIOR DISCOVER CARD ACCOUNT ''. 
My bankruptcy, which was fully discharged in XXXX, and the XXXX issue with my Discover Credit Card account included in my bankruptcy, are both more than ten years old now, so why did Discover deny my credit card limit increase based on information that is past statue?
