You definitely deserve justice if you were wronged, but the only way to get it is to demand it! Talk to the person in charge. You don’t have to be rude, but you do need to stand up for yourself. If you are overlooked at work, you need to talk with your supervisor and explain why you feel you were slighted. This is an art you need to practice, so be on the lookout for friends who have been wronged and come to their rescue.
