Why must i wait 14working days just to refund money you see is incorrectly paid due to your app error

I am still waiting on capitec to resolve my query R1500 is a lot of money and we now could not even buy griceries because i had to pay R1500 to the intended person while i wait for capitec to reverse the amount paid to 1st for women account which its still a mistry how do a saved beneficiary's account for capitect suddenly changes to a standard bank account holder but when you check your saved beneficiary account is correct on your app abd same i paid from my nedbank last month and went correcly to the correct account whats different with capitec????whether you send authetication first or not how does your saved beneficiary account can change to another bank account holder. Not making sense a d i need my money,im a bread winner and a mother of 3children. We running out and have no cent in my name right now
