ABSA fees on closed account

I cancelled my ABSA credit card by telephone on 6 March after a *****ulent transaction (strangely on the same day it was delivered by courier). The consultant said I would receive a call to advise me on balance settlement - this never happened. I then paid the full outstanding balance on 14 March and requested that the account be closed the following day. Again a follow-up call was promised to discuss the cancellation of account fees that were raised which I felt shouldn't have been payable if the account was closed when I asked the first time. The call never came. The fees were settled by debit order this month, and it looks like ABSA has raised further monthly fees on the account in April! Is it the plan to keep taking fees on an account that I've instructed to be closed twice now? I would appreciate it if the March and April fees can be reversed - the incompetence is staggering.
