Charged twice for flight bookings

Booked flights online on 1 January. The full amount due went off my credit card on 2 January, but SAA also put a duplicate hold on my card for the full amount. In effect, I was charged twice. This hold was only released on 13 January after several emails to customer services. They forward the query to SAA's financial department, who decides when they want to look at your query. No way to contact them directly and also NO feedback from them. So you are left waiting for however long they want to take to resolve the issue. I will never book with SAA again. Not worth the stress if their financial department cannot be bothered to give proper feedback.
