I have not heard of many success stories wherein Citibank recons are concerned...but since you took the inquiry it is worth a shot.
agp posted this information on another thread back in August: http://creditcardforum.com/general-credit-card-talk/5287-citi-recon-number.html
"There's no number to call, but you can write to:
CitiBank Executive Review Department, P.O. Box 6000, Sioux Falls, SD 57117"
You could also try Tweeting the AskCiti team on Twitter to have someone there call you. They are top level reps so it could be worth a shot. You just Tweet them a general question such as "Denied for a card, who can I talk to about this?" and they will send you a private message requesting your phone number. But I think the above address is your best shot.
Emphasize in your letter that your inquiries are the result of auto loan "shopping" by the dealer and you were under the impression that several inquiries tied to an auto loan or mortgage are usually counted as one by most creditors.
It could also be this: "9 Retail Cards (2010-2012)" ouch! 9? Are they all still opened? Even though the inquiries from 2011 and early 2012 shouldn't be a decisioning factor in your recent denial, most creditors see that you have opened 13 cards in less than 3 years and they get a little nervous.
