Closed Cheque Account Still Active

I'm very disappointed in ABSA service. I went to ABSA Pretoria CBD on the 24th November 2014 to close my cheques account I was assisted by Vusi Sindani ***. I paid the charges fee and was told the account has been closed and he opened a new one for me. Now only to find that the account is still active and now it has accumulated charge fees of R3258.58. I would like ABSA to respond to me and tell me who is at fault here as I am not going to pay that amount that was caused because of their consultant's negligence and uncaring behaviour for customers.
