Capitec safety mechanisms are poor

I have a company by the name of Shopify who are busy debiting my Capitec account without permission. I reported the matter to Capitec, and I was told that I must stop my card which I did. Now the same company is back debiting my account again. I told Capitec and now they want me to close the new card. How is it that they can't stop the company from accessing my account. Their solution is only to stop the card and get a new one?! Wow! I will keep doing this until when! The unauthorized debiting was supposed to stop with the old card.
