Poor customer care and incompetence

I am very much disappointed in Fnb service, on the 30th of last month I paid my credit card 450,& my account was also debited 442 which was due..I called on Friday 4th an d 5th on Saturday to ask when. Will it clear as it had been on auto pending and Friday was the 3td working day. When I called in Saturday as I realized it was now on reversal auto pending I was told by Lesogo that it will paid in back 442 into my account as I had made payment of 450 on the 30th, today still nothing and I called SPK.to Florence she told me there is no such cause I wanted to know what is happening now I asked her to delete the debit order and I will make payments myself she says for security reasons she can't I find it ridiculous as I was the one who had to call in and instate debit order on the account in the first place when fbn failed to do so. All I want is to pay my account manually that way I will not have to deal with anyone who will give me different stories more like *********** .
