Angel Guest House are refusing to pay back my money

I visited this guest house on 10 October and was told to make an EFT payment before checking in. I mistakenly made a normal payment (Capitec to Absa) and since it was on a weekend, it would only reflect on Monday and I was going to check out on Sunday. Therefore, Vasco who is the manager on site, advised that I make a second payment, this time as an immediate payment so that it could reflect immediately so that I could be given a room. Then he said they will refund me the first payment once it reflects on their side on Monday. It is now 27 October and I have still not received my refund. Everytime I call Vasco he says that his boss (the hotel owner) says that the money has not yet reflected which is obviously a lie. They are clearly refusing to pay back my money
