Missing RP

I recently bought some RP to buy a couple of skins for myself and a friend. The purchasing part was easy even though I used the OpenBucks one with my Subway giftcard. After I purchase $25 US dollars worth of RP I bought Dark Star Varus and was hoping to buy Dark Star Thresh for a friend when my client crashed. I restarted my client and came back to my account to suprisingly find to RP left. I checked my purchase history and the Varus skin was successfully purchased but, 1350 RP doesn't equal the 3450 RP I bought. All i want is my RP to be given back and for you to fix the side effects of my game crashing. Thank you, Fanthor013
