Charged twice for the purchase of one champion

Hey guys, To my amazement I log in today, and I notice there is something wrong with my total RP, so I go into my account purchase history, and I see that I have been charged twice for Hecarim - I bought him on sale yesterday for 440 RP, however, 2 instances of this purchase is shown in the purchase history. I know that Riot has a no refund policy, but I just wanted to know if this was a bug, or if there is just small possibility that they might refund my RP. Thanks in advance!
