Capitec ********** transaction authorisations

On the 31st of March 2022 my cellphone and laptop were ****** out of my office at work. I worked until 22:00 that evening and our offices do not have an alternative to make calls. Later that evening when I got home, I discover that an amount of R6 290.00 were cash transferred out of my accounts. With no cellphone, no communication could have reached me to see these unauthorised transactions being performed. I didn't know about this until late that evening and I didn't have a phone or computer to stop the card during the day. Capitec do not want to help me, because according to them they said that the person did not struggle to get access to my account. I need assistance in getting this resolved.
