Short version. In Omaha you can use two cards from hand, three cards from board.

OP holds: 6-7-8-9
Villain: 9-10-J-Q

Board: 5-5-6-7-K

OP: uses his 8-9 to make a 5-6-7-8-9 straight.
Villain: uses his Q-J to make 5-5-K-Q-J for a pair of fives.

The pot was shipped to the Villain not OP which was wrong.

If this is what the hand logs actually shows on BetOnline's side: this is a case where the only natural response is to immediately refund the player apologize and then go into panic mode getting whatever quirk exists in their software fixed as fast as humanly possible. Unfortunately for OP he's most likely talking to support reps who don't even no how to play Omaha or even understand his question. He's now getting the usual BetOnline run around.
