transfered money into wrong account

I transferred an amount of R 420 from account *** using my cell phone to my friend using his number ***. a day latter my friend told me that he had not received the money. i checked my statement which reflected that the money was transferred. we both went to capitec mall of the south branch and we were told that the money went to another account. they further told us that the account which the money was transferred to was dormant. they said they can’t reverse the transferred money and i must institute a civil action against the recipient of the money. I did not know the details of the recipient nor his contacts. what was strange is that my friends cell numbers which he has been using for more than 20 years was linked to someone’s account, a fact which capitec could not dispute. I went to two courts as per capitec advise. the courts told me they can’t help me as I don’t have the details of the recipient. I have been sent from pillar to post but no help. I am extremely disappointed because I need my money and capitec doesn’t help me. I am tired of going to courts , as I need to take time off from work without success.
