Product: Credit card

I 've had an account with Navy Federal since XXXX and in XXXX of that year they approved me for a credit card with a {$500.00} limit. After some time I added my wife to the account as a joint card holder. After about a year, I requested for a credit limit increase which was approved to {$20000.00} limit. Recently this year I requested for another credit limit increase and was declined for that increase. The reason was " Excessive credit obligations ''. FYI, between my wife and I, we have less then {$7000.00} outgoing in expenses. Our gross monthly income is OVER $ XXXX monthly! I ask you, DOES THAT SOUND LIKE WE HAVE EXCESSIVE CREDIT OBLIGATION???? I attached both my wife 's and mine paystubs to them for proof of our income. Here are the emails that were exchanged between Navy Federal and I during this process : Your Message XXXX/XXXX/XXXX : I am challenging the decision for the credit limit increase. The letter I recieved states " excessive credit obligations ''. Base on my research, my obligations are as follow : XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX navy fed XXXX navy fed XXXX XXXX XXXX XXXX XXXX XXXX That put the total at $ XXXX monthly outgoing before housing expense. XXXX has the same accounts and XXXX additional auto loan for {$910.00}. That brings the grand total to {$3800.00}. If we added {$3000.00} for mortgage and housing expense that will put the grand total at {$6800.00}. I 've attached my most recent paystub with a YTD of {$XXXX} which would put my avg monthly gross income at {$XXXX}. These figures DO NOT include XXXX income ( attached as well ) which is just under {$XXXX} a year. So the only question I have is HOW CAN I POSSIBLY HAVE " EXCESSIVE CREDIT OBLIGATIONS ''?????? 
In addition, my credit card balances are ALWAYS paid in FULL on the due date. Also, between our savings accounts with Navy Fed, we have over {$70000.00} in cash!!!! 
Please explain how you derived at your conclusion?? 
PS. A {$15000.00} payment was just appied the the cash rewards credit card and I will be making another payment on the XXXX which will cover the entire statement balance Navy Federal Response XXXX/XXXX/XXXX : Thank you for your message. Because we take our members ' concerns seriously, we conducted a second review of your application. However, after careful consideration, we have determined that we must stand behind our original decision. At this time we can not qualify you for any additional unsecured credit in addition to your existing credit card account you currently have with us. We regret that we are not able to reach a more favorable decision at this time Your Message XXXX/XXXX/XXXX : XXXX. The term " excessive credit obligations '' would mean the consumer DOES NOT have the ablility to repay the debt. Mathematically this does not make sense! Base on my income alone, I calculated 33.5 % DTI. Please let me know if my math is wrong. Not to mention the fact that I have over {$XXXX} in my account and XXXX has {$XXXX} in her accounts. Please provide me with a DEFINITIVE reason as to why!! So far all you 've done is dance around the reason why. I know you pull XXXX but did you pull XXXX Or XXXX?? I do n't have my XXXX score but the XXXX has more accounts and should be more reflective.
