REVERSE

my niece just made a mistake depositing R1500 to the wrong person, her monthly wage she owed to someone, who helped her now she has realized her mistake called CAPITEC they refuse to reverse it, they say they can c, they also did a security test and she passed that but they refuse they say they need to get permission to that person, how are they going t do that, they say she must get a lawyer, with which money? it is not fair, so people be aware CAPITEC IS A **** THEY CANT HELP THEIR CLIENT IN TROUBLE, other banks can reverse why can't they?
