Accidentally transferred money ti the wrong person and the bank is taking me from pillar to post.

I accidentally transferred R15000 to the number *** belonging to Ralph Nkoana instead of Lerato Miya on ***. Seeing my error I immediately call Ralph who still do not answer my calls & hv switched his phone now. I went to Pretoria Arcidia Branch & was adviced by Mbongeni Hlatshwayo who insinuated that I go make an affidavit which will be scanned to head office. As Risslyn branch is next to where am staying I passed there n where Nthabiseng Mojabi alluded it's a Civil matter & I need to open a police theft. Indeed I went an open a case. Now I've just called Capitec client services & I was told it's a civil matter I need to go to court to open a case. I have already opened a case of theft with police & awaiting case number. The treatment is not good at all. Where am I going to get my money because as bank they have a right to reverse the money . They did not even consider giving me a reference number on ally calls. Calls are recorded as they always say. I just need my money. Thus is not the first time Caputec is doing this to me.
