Unsuccessful money reversal

I am so disappointed with Capitec bank. On the 14th of January i transferred money to the Bidvest account which I sooner found out that it was a ***** account. On that same Saturday within 30 minutes of transection I went to the capitec branch to reverse the money of which was normal pay. They made a recall and assured me that I will get a feed back within 7 days of working days. I never got any feed back so i went to the bank branch to check and they told me that the reversal wasn't processed because the recipient has already used the money. I asked to escalate the incident and the feedback was very disrespectful and unprofessional. How did the money got processed but i have reversed it after few minutes of transection!!!? Capitec is full of kaaak.
