Pathetic Credit Profile Killer

Can somebody please get RCS to close my closed account and update my credit information with Credit Bureaus? I've sent paid up letters and provided context, this (demon) company is refusing to assist. I spend a whole week not working following up with the "correct department" but the line never caught. I regret this company nor would I recommend it to anyone. No one can help clear false information that this monster is blatantly spreading about me. Please update my info and call me.
