What was the reason they denied the cli? I wouldn't be so quick to cancel it seeing that you're only 100 away from the acceptable pc limit. Work on the reason the cli was denied and then try again. Also have you checked if you pre qualify for another citi card?
I agree. If it was me I would call them and offer them 100 bucks to PC to the card I want. Granted that you are allowed to do that after denial. I did this with my first discover account. I've found these companies like when you are willing to pay up. IDK shows determination in their eyes I guess. Also less risk if you prepaid a CL. Then again, mine was secured at this point. Also a diff company!
