Capitec credit card ***** when only Capitec have my details

On 06 July 2022 I made Capitec aware of a ********** payment that had been taken from my credit card. The same payment had also been taken from my husband's credit card. There were only 2 places that had both of our credit card details - a certain online store and Capitec themselves. They told me the only way to stop it from happening was to replace the card, which I did. I have not entered my credit card details into ANY platform and yet the same ********** payment occurred yesterday (11 July). The only place that has my credit card details is Capitec As is expected, they do very little to assist and say they will give feedback within 30 days.
