Hi I figured I'd put this in here because I'm sure somebody will search for it. If you're a Platinum cardholder with Capital One, and had some type of secured card with them (I ), bad news. Talked to a CSR with Capital One who told me any type of secured card will at least for the foreseeable future not be considered for any CLIs unless it is a NEW account. So that means if you've had the card awhile like i have (2013!) it will always have whatever credit limit you have now.
She did say eventually they may "graduate" these cards again, but basically what i did -- applied for an unsecured one a few months back and got approved -- is the only way you'll move to an unsecured card. Of course, if you close the account they'll refund any of your deposit (I desposited an additional 50 to make it 250) but yeah, that kind of sucks.
Ah well, going to keep that card a while longer until i get a new higher limit card from another carrier and close it out. No sense in keeping it anymore if that's the case.
