Edgars Poor Service // Account Closure

I am so fed up with Edgars, the RCS Group especially. In December, I went to Edgars Kolonnade Mall to close my account. I paid the outstanding amount on my account and the lady informed me the account has been closed and the Rcs group department send me an email saying cancelation of edgars account. Up until now it is still active and no reply whatsoever from them... Not the enquiries department,, rcs group department. I have send them proof of this and still no response only receiving statements and ticketnumbers with no feedback and evenntried to solve this telephonically. I am not going to be responsible for this outstanding amount and my credit record is busy becoming very poor because the employee at Edgars informed me incorrectly or I am really not sure what happened. I have proof that i went numerous times to. Make sure they close this account and still nothing. Edgars is really pathetic. Would really appreciate it if you could help me with this matter. Regards, Michelle.
