I already purchasing game item yesterday. It was written unable to purchase. I though my transaction was failed so i tried again and again but it still unable. And now my credit cards over limit. What happened here?

I dont know what happened, i get charged from my father visa credit card. I play Ragnarok Valkyrie Uprising game which can buy shop item(name ruby). First time i tried to purchasing 210 rubies it cost 189 In Rupiah(Indonesian currency) but it was failed and showing dialog box unable to purchase ruby. So I tried again and again bought rubies with different values (10 rubies,50 rubies,210 rubies) but that unable to purchase dialog box always appears. I though the purchasing rubies transaction was failed. Then i was trying to find whats wrong and get some information from the internet all day until i calling my credit card (Citibank/visa) technical support, he said i was already did some transaction for this. i ever did rubies transaction before and it was completely working. Please help. wheres my money gone? wheres my 210 rubies? I even cant check my billing information and purchased history cause my credit card is declined by itunes cause over limit. Pls give me respon to solve this.
