RCS-Dion Wired Enable ***** on customer accounts

What must I do to close the account? There was a ********** transaction in 2018 on RCS-Dion Wired account I closed 3 years ago. I sent documents (Affidavit and ID) over and over. It was only resolved after 2 months of following up twice a week. I am now receiving statements again for the same account, which show that my account is still open. I also requested that a credit limit be reduced to R1.00 while RCS tries to close the account, this was never done too. I will never recommend RCS or Dion Wired to anyone.
