Missing amount in my account

I do not understand how Capitec can take money out of my account without my consent. R1300 is missing because someone claimed they know me so capitec just gave them that money without consulting me. When i went to one of the branches they called their Head office and all they did was give me the person's cellphone numbers which i called and the person is all the way in KZN and she claims she knows nothing about the money. please help.
