Very disappointed no answer

So disappointing that no one in capitec bank is willing to help. I have made a eft payment by mistake to a wrong beneficiary. I have went into the bank on the 25th and asked for a reversal. Up till today no response from the bank as yet. And I can't even get info of the person I paid. I have made a payment to them 2 times last year but I can't remember who the person is and why I made the payment to ask the person back for the money. And the bank as well is not willing to give me any info at least if I get a name of the person it will ring a bell in my mind of who the person is. I really like to change my bank cos I'm so disappointed as it is 3000 Rands I lost and my bank not helping at all.
