i bet once your plat. card expires they will issue you a signature card saying they have decided to upgrade you. I am real curious why they stopped offering the plat. card too? i actually was wanting to downgrade my signatrue card to the plat. since it doesn't report CL but that ain't gonna happen now. I believe you need around a 720 fico for signature card.
I'm not sure if I really want it. I was hoping to get the Platinum. Oh well, on to plan "B", once I figure out what Plan "B" is.
