Dis-earned 

When you do something that causes you to lose something that you had earned, you dis-earned it.

Mom: Molly I was going to get you a gift but not anymore after you were so sassy. You have dis-earned it!
Molly: That's not fair!

Disearned 

To lose something that you had earned as a reward because of your actions. Unearning it. The reverse of earning something.

Mom: Molly you are not getting that treat . You disearned it because you were sassy to me.
Molly: I hate disearning something :(
