I applied for a line of credit through a furniture store. I only needed a couple items there. I'm finally done paying it off and will never use it again. I was told that closing an account is bad, but I don't have any need line of credit any longer and I don't want to just keep buying furniture so the card stays active. Did this account help me raise my credit or is it now going to hurt me because there's nothing more I can do with it?
