Capitec stole my money

I recently had money ****** from me, and the bank was not able to send all my money back that was ******, which I don't understand because they have insurance on things like this, I have requested all my feedback in writing with proof which I still have not gotten and it has been 2 weeks later, I still have a lot of money which needs to be recovered. They tell me they were not able to stop the transactions but to my knowledge it takes a day or 2 to send money to a different bank, and I found out my money was ****** on the same day. I am pretty sure that this was an inside job. I am very disappointed in capitec Bank not refunding all my money that was ****** and I am going to take things futher. I want my money
