Capitec arrogance/ incompetence

I would give Capitec Bank 5stars for revolutionising banking practices in South Africa. But now I am peeved by the way they have treated me over the last two weeks. On the 2nd of July I made a cash send of R500 and could not redeem the voucher. I immediately called the helpline to resolve the problem and after three visitations to the bank, my money is still not refunded back to my account. They claim to have a backlog. My question is... How long does it take to refund R500? Two-three weeks or months? I believe that Capitec is just being arrogant. No bank takes that long to reverse any amount.
