Wow, just logged onto my account and there was $1000 CLI to my Cap one card. I've never gotten an auto increase from them 
They are one ungrateful bank!!
Maybe they've been reading your comments about them?????? 
I guess it is the season for giving, I just logged into my Cap 1 account that I've had since 07and never gotten a cli, and to my surprise a auto increase for $1000. First Target and now Cap 1 and $200 from Orchard. That's a grand total of $2200 in a matter of 2 weeks. It is indeed begining to look a lot like Christmas
I never left $750 in my time of being with them. And due to their greedyness(well mine also), the account is now closed
Chase however just automatically increased my Freedom Card once again. March of this year I went from $300 to $800, and this month I went from $800 to $1,100. Not the best CL but not bad for an 18yo I guess.
