Erroneous debits from Absa

Topped up a student loan in March,and the consultant saint both to ask if I need credit protection.When she handed me the quote and I advised her that I had life cover,she assured me that it would not be billed on 25th March and I'd it did, I was to email Absa and notify them.I went back into the branch on 30 March,and another consultant helpfully assisted me in sending an email to credit life department requesting that the credit life be cancelled.On 25th April,the debit went through again.When I queried with absa,they rep**** that they have 39 days to sort out.On 12th May I called the call centre,and was advised that a manual payment will be done on the 17th.I called the call centre again on 25th advising of no refund and was advised that there's a backlog and payment will be done within a day or 2.It's now the 30 May and I'm still waiting for my R1500+ refund
