People do not despise a thief if he stealsto satisfy his appetite when he is hungry,

but if he is caught, he will pay sevenfold; he will give all the goods of his house.

-Prov. 6:30-31

We’ve heard that the devil is a thief in John 10:10. We also see in Proverbs that if a thief is caught they must return seven times what they took. 

Instead of being down when someone rips you off, recognize that it is the enemy working in them and claim 7 fold return rather then losing your joy. Watch and see what happens.
