Celestial Item Can't be Refunded

I purchased a duplicate “Legplates of Sagacious Shadows” from August Stone Fragment vendor by mistake in Mists of Pandaria Classic. I attempted to vendor the item for a refund but was only given gold. I then vendored the second item thinking I had selected the wrong one to vendor. It also gave me gold. I never equipped either of these items but was never given a 2 hour refund window. I just want my fragments back. Please refund.
