Transation of money to wrong person

I have been unfair treated by capitec bank. On the 25th of february i tranfered R2500 to the wrong number by mistake. On 26 the next day i went straight to the nearest branch hoping they will able to reverse the money they told me that they won't went thtough to the account of this person without his consent because this person doesn't take their calls they went to voicemail. They told me to go to small court claims but they didnt help me and told me they don't dealwith this kind of matter ...I went back to capitec they said there's nothing they can do for this matter just like that.They claim it's my fault to transfer money on the wrong person.My fear is that they freeze the money only for 8days so by Wednesday this person will able to use this money.What can i do
