Very disappointed

Vodacom bucks is the worst, I bought the smeg kettle that was on special on the 12th May and my order went through, now 2 days later they tell me they are out of stock and they deducted my money, I told them I don't want my money but my order as my money was already by them. Now I see on the Voda bucks my order has been canceled but all along it was still pending awaiting stock at I had requested , now can they please refund me my money
