RCS- Edgars ******** account holders trying to close accounts

RCS is running a **** after taking over Edgars accounts. The company makes it hard to close the account and even after requesting the account to be closed via email, which a consultant acknowledged receipt of, they still want me to pay amounts that were charged after I closed the account. A consultant said I was supposed to request a settlement amount after paying my balance, which does not make sense because I have paid my balance and asked for the account to be closed. I have called the call centre and the consultant said that she will request for the charges to be reversed and I will have to make a payment of R20 or so, which I believe is a ****. I am still waiting for the email stating the reference for the call and confirmation that the account is closed, just as I waited for 3 months for them to reply to my email of the account closure which never came. Edgars and RCS are robbing customers because of their own ill administration of their accounts.
