I opened my Discover IT card on 7/14 and was approved for $12,000. I decided to request a cli on 10/28 and was denied for "Insufficient experience with current Discover card credit limit." Then on 10/30 I get an email that they auto cli my account $1,200. Hmm... Whatever I will take it. Well I just decided what the heck let me try again just now. I removed my credit freeze from TU and requested the cli...I just knew I was going to be denied again and then BOOM "Your approved for credit line increase of up to $3,000." This is now my highest credit limit of $16,200.
