Incorrect fund transferred to someone s account

I don't know why as South Africans we still using Capitec Bank..the service sucks! everything with them .am not sure how can we trust them with our money's..I called today for assistance I currently sent the funds to a wrong person's account so I called the number that they always saying if you have a problem you should call(***) is the one that we reporting to it when you experiencing problems like : reporting *****ulent or if you have any issues..so what happened I called an I find the guy by the name of Bonginkosi he greeted me and I agreed with language which is (isiZulu),he repeated greeting me in English so that I can switch off to English I continued talking (isiZulu) he pretended that he can't hear me because I was speaking isiZulu he dropped the call ,I called I again I find the lady speaking English she kindly assisted me very nicely and I told her what happened..she apologizes on this Bonginkosi guy behavior...she sad I must call around 7:00 of which I did..I find the guy by the name of Bonga I clarified my problem to him that I transferred funds to a wrong person can they reverse them ..the guys sad Capitec protocol does not allow to reverse the amount they not going to help..what a frustrating moment I had..he couldn't help! Mistakes happens we human beings why if I did the mistake of mistakenly transferring funds to Capitec I can not reverse them ! Why is only Capitec who can't do the reversing other banks they do are they *********** or the bank itself is *********** that what I want to be clear on ..if so how can we trust the bank that is *********** with our monies with the staff who only assist the English speaking people only yet we have 11 official languages in South African
