Standard Bank premature debit order | Standard Bank

Standard Bank changed debit order date without consultation.

Standard Bank took it upon themselves to change my credit card debit order date from 28 December to 15 December with 1 day's notice and no concern for whether I had the funds available to make the payment. My account is now in arrears and when calling the call centre I get told there is nothing they can do about refunding me. I am also annoyed because this does reflect negatively on my payment history as I have never defaulted.
