Accidentally sold item and got no refund.(Blackrock Server)

Hi, I play on the Blackrock Realm and I've saved up for the Pyro Rocket for 50000 honor, I bought it from the Rewards Vendor about 15 mins ago but in a moment of stupidity, I tried to use/equip(Right Click) it while the Rewards Vendor was still open so I sold it back. I went to the Buyback tab and it's not there and I got a message saying Refunded for 50000 Honor Points but never received any points... Please help! :'( (Character Name: Johnnydeep)
