How many times are you going to deduct from my account for the same transaction?!?!?!

This is the second month in a row where my account gets incorrectly debited thrice for a single transaction. Last month the same thing the card machine says declined and then it goes through. When I contacted standard bank last month when this thing happened I was told it was a technical issue and somebody from technical would contact me within 48 working hours, the 48 hours came and left with no contact. When I phoned back I spoke to another consultant who told me I must go back to the shop and ask to reverse the transaction, a transaction that was standard banks error. I had to drive a couple kms to fix a problem that is clearly now reoccurring. After a heated conversation with the consultant where I was told she wasn't even sure if there was a technical issue after the previous consultant told me that there was an issue, they magically returned my money. In this instance the amount was deducted thrice from my account. The error was correct only to be "corrected" as in deducted from my account again. Honestly bad customer service and technical service. And now I'm probably going to have to waste my airtime and argue for my money again. Thanks standard Bank you guys are truly giving me wonderful ****ty service.
