No 2 step authorisation on *****ulent online purchases

I just had a bad experience where a *****ulent purchase was made from my card last week and while the bank did refund that amount, and I had to stop the old card and go to a branch for a new card, I am now sitting with another amount that went off on the same day from the old card that was not picked up, also a *****ulent purchase as it was not made by myself and when contacting the bank now I am once again struggling to get my money back since I DID NOT MAKE THE PURCHASE and there was no 2 step authorisation done on the purchase from the bank's side. I am getting so extremely annoyed with the service from Std bank, i just want my money back from the *****sters and Std bank to UP THEIR SECURITY so that 2 Step authorisation will be needed on EVERY ONLINE PURCHASE
