Debiting an amount without informing me - POOR business, Standard Bank!

On the 12th of December 2017, I wrote a complaint on HelloPeter about the fact that I raised an objection to an amount on my credit card on 26/10/2017, which had not received any attention from Standard Bank, despite my numerous calls. You then responded and credited the amount to my account (i.e. you corrected the error).

Lo and behold, on my January statement, you debited it once more! Did you think I wouldn't notice, because it's a small amount? Or did you think I just wouldn't take action? I AM A CHARTERED ACCOUNTANT. As I explained to you before, the parking lot meter at Sandton Convention Centre wasn't working - I cancelled the transaction and moved to a different machine, where the transaction went through and my parking ticket was stamped. However, on my credit card, the transaction went through TWO times, even though I CANCELLED the first transaction.

Well, congratulations, I am now using you as an example of how NOT to do business to my 283 post-graduate accounting students at a private university. We're having an absolute field day analyzing your business transactions.
