Online order not processed second time around

I have been a customer of Naartjie for 6 years now. I buy all three my kids clothing from them. Because we do not live near the shops, I make use of Naartjie's online shop on numerous occasions. Two months ago I placed an order with Naartjie and paid through payfast like I always do. Then I discovered it did not go through, so I used the money in my Payfast wallet for something else and just left it there. On 4/3/2016 I placed an order again. Then discovered that the order was not processed again. Payfast wanted to refund me but I actually wanted the items. I could easily just leave it there and placed the order the 3rd time, but I discovered one item was now sold out on the online shop. I said to the correspondent that I want them to complete the order for me as I really wanted that item. Then they just let me know Payfast will refund me?? In a situation like this I expect them to try to save the day and at least help a customer out. I explained myself to Ebrahiem but I just get the same kind of emails back. Never did I receive bad Naartjie service before. Very disappointed!!!
