Credit card debt? Or does student loan debt count as well?
		
		
	 
No they are separate. On your report there are two non-deliquent types of debt. Long-term installment debt (car loan, student loan, mortgage), and revolving credit (CC). High utilization of revolving debt means having a 4k max CC, a 5k max CC, and a 1k max CC, with say 8k spread out over them all. You'd be at 8k/10k available, or 80% utilization, which is bad
Though from the sounds of it you seem to be at 0% utilization, call your bank and protest. When they lower your amoutn of available revolving credit, it hurts your score
