PAID OFF MY ACCOUNT 431 DAYS AGO BUT RCS STILL DOES NOT SEND MY INFO TO TRANSUNION

Guys can RCS ensure that my name is cleared at transunion, I am tired have been trying to call and email but I am unfortunately not winning. I closed my account March 2018 and have never even before closing it skipped my installment, but apparently it shows that I have not been paying my account. March 2019, I then realized that my profile still reflects RCS and kept in touch with it to date transunion still says it still have not received any communication from RCS. Last week I called RCS and they literally **** to me saying they have send out a communication to transunion, today I called transunion to check unfortunately they haven't received anything. I am tired don't know what to do anymore, it has been over 431 days after the closing of the account. RCS is definitely not willing to help me at all.
