Capitec Bank-Unknown online purchase/ONLYFANS.COM LONDON GB

There are seven transactions of R277.81 tonight from ONLYFANS.COM LONDON GB. I don't know about these transactions. I called Capitec 24 hours call centre. capitec employee has told me that they will charge me R80 for investigation for each transaction and R70 for a new card and I have to wait 8 working days for this issue to be resolved, Capitec Ref No: 832 411 40. How will they charge me R80 for each transaction that I don't know, I have never used this card for an online purchase. why I have to pay for Capitec poor security. how can someone access the card that I have never used to purchase online? i have been a loyal customer for many years. I'm so angry and disappointed by this service from Capitec. I noticed that there are many people complaining about this issue. instead of making sure that your app is secure, you are busy charging us R80. We losing our monies but Capitec is not assisting us.
