Rage deliberately bring down my score

I closed my Rage account November last year but for some reason under my ITC it still reflects which contributes towards my credit score negatively I have sent an email and clearly noone is interested in assisting which means they are deliberately trying discredit my score. At this point I don't knew what else to do besides raise this with the credit Bureau cause I can't even get a home loan. I'm stuck with thier information that makes my credit looks bad
