Capitec wont pay back my money

On Sunday (Jan 5)I transferred money to a fellow Capitec user but he never received the money, I called the customer care and after speaking to several *********** agents I spoke to some guy who indicated to me that indeed he was able to see that I made a transfer that never reached the intended recipient, despite the admission, they still insisted on a 48hr investigation which ended on Thursday (Jan 9) 8am. They promised me at the end of the 48hr investigation I'd receive back the money or it'd go to the intended recipient (neither happened). I called to find out why, gave them the reference but despite that it seems like its a brand new issue to them (how frustrating), and then after spending so much airtime they told me the issue is gonna take 7days to resolve (remember it was 48hrs, now its 7days and they have admitted that indeed I made a transfer which never arrived). Its so infuriating, I need the money and they are unnecessarily holding on to it for no apparent reason. It seems as if the only language they understand is for you to go on a national radio with the issue or make them trend on Twitter for all the wrong reasons, and its precisely what I will do if they will not have refunded me by Monday.
