MTS Ate My Items =(

So I put up 2 60% Glove Atks for 2300 NX. Then I see a whole bunch of 60% Glove Atks for 1200 NX each, so I'm like, oh what the pineapple, I'll buy them. Then I decided to just sell them all for mesos, and I canceled the 2 60% Glove Atks I put up earlier. Now, I must've canceled at the exact pineappling time as someone bought it. My 2 60% Glove Atks are gone and I received no NX either. I checked my 'History' tab, and it says that it was sold for 2300 NX...I'm mad I want my scrolls back I'm not even gonna try logging a ticket because they're gonna do nothing about it.
