Thanks guys! I called the number listed on the backdoor thread. 1877-379-8173 but the rep transferred me to another line so I'm not sure what that number was. I have had the card for over a year. It started at $300 then bumped to $900 where it's been stuck for a while. I think I was finally able to get an increase because I've been working hard to decrease my utilization thus increasing my scores. They aren't great but I'm getting there.
