I learned my lesson with Capital One and their CLI. Finally after getting tired with such a small line, I started a chat with a specialist, and threated to close my accounts, all three, to which he replied back with a CLI, and he also signed me up for another series of credit steps so in July I will receive another CLI. I did end up closing one of my accounts with them and when they asked why I wanted to, I just told them that my credit lines with them are not growing with me, the CSR then told me that Capital One is very conservative with CLI's. I'm glad they finally told me.
