Debit order

My debit order for my credit card went off today and my payment date is the 20th of every month. I spoke to the Team leader and her Name is Gugu Maphosa on ********** 000. They are saying that they can reverse my payment but I have to manually pay on the 20th. This is nonsense as I did not ask them to deduct my account on the 15th. No notification was sent to let us know. This is bad service. They should close down as they have a bad customer service. I want my money back Today as they took my money today, and they must deduct on the agreed date as I signed the contract.
