Capitec weak and lack of controls with online transactions

As a Capitec client and an account holder I find this rather disturbing and being inconvenienced by the weak and lack of controls that the Capitec has with unknown online purchases that’s been going off my account. Worse of all no one at the Capitec branch or client services can assist me with reversing or blocking online transactions going through my account. I find it rather unprofessional for such a huge bank trying to gain a market share in the banking industry to have such weak or lack or controls and no contingency plan to assist their client when there such emergency. Because of Capitec my family and I will not have funds available for Christmas. Capitec Management should contact me and resolve this matter ASAP.
