Last week Thursday I made a purchase at Tile It but due to loadshedding there was network issues my initial transaction was reversed and declined according to the shops handheld card machine I then swiped a second time and this time it was successful. I got charged twice of which was not supposed to happen. I check my banking app and there indicates the 1 transaction as unsuccessful yet the money went out for 2 transactions. It's going for a week now and the funds have not been refunded yet. How long does it take Capitec to reverse the funds this is unacceptable from a banking institution that's still trying to make a name for itself in the south African market
