5 days later and still waiting on assistance from credit card division

I'm very disappointed with ABSA credit card division. Despite having a debit date of the 5th of the month, I am expected to settle the minimum debit amount 5 days prior to the debit date (i.e. the 5th of the month), as ABSA will activate a debit order for the amount due regardless of whether you have settled the outstanding balance in full or not. This month, I paid the amount due by the 3rd of January, despite paying the same amount was taken of my Cheque account on the 5th of the month. I phoned in on 5th January and asked the customer service person if they can confirm which clause states that ABSA requires 5 days to process a payment to a credit card, they could not confirm this. I asked to speak to a supervisor and the call was disconnected. I called in again and spoke to a second customer service person, requesting to speak to the supervisor, the person then advised they will be able to assist by logging a dispute and requesting that the amount taken off my cheque account be credited back to my cheque account with no charges - and if I would still need to speak to a supervisor if this was done. I agreed that if she could assist with this then I do no need to speak to a supervisor. I was also promised that a copy of my credit card contract will be emailed to. This was 5 days ago and I have not been credited to my cheque account, and have not received the contract via email either. Very disappointing service...or lack of service!
