No security on my Capitec account

I was recently hacked through my Facebook business page (which is now blocked by Facebook) The hacker managed to access my Capitec account and withdrew two amounts of R4079 . I have an online purchase limit of R2000 which was bypassed by making it a recurring payment. I received no notification sms from Capitec ( which would have afforded me the opportunity to quickly stop my card on the app ) When I logged the call to Capitec, I was very clear about the fact that I teach swimming and cannot answer my calls whilst teaching and had a special request of receiving a text in the event that Capitec couldn’t reach me… asking me to return their call. I did receive one such text and instantly called back to a recorded conversation with Capitec. I was at Capitec Meadowdale mall yesterday and asked to follow up as its been close on 2 weeks since the investigation started… only to discover that they have closed the investigation on one of the 2 amounts with the excuse of not being able to reach me. I have not received another text as notification of them attempting to contact me. It feels as though they are trying to get out of reimbur*****t this way. My main ref no is ***8 and my follow up ref no is ***5.
