Worse off after being put on a different fee plan

In the middle of March, I went into ABSA Ferndale Branch to discuss various items - one was bank fees. I was told I would be put on a Pensioners Plan and I wouldn't pay any fees. Up until this point, I didn't pay any fees on my cheque account. My next cheque statement reflected a whole bunch of fees from that day onwards. On querying this, I was told the fees would be reversed. Only part was reversed at the start of the next month. My query rectified this. I still pay bank fees on my Credit Card. The following months statement resulted in the same thing. Only partial reversal. My query of 10 days ago has resulted in no correspondence or correction. This is unacceptable. When asked to be put on my original plan, I was told it couldn't happen. Please put me back on my original plan or a 53 year relationship with ABSA will be in jeopardy.
