restitution
Step-by-step explanation:
Based on the information provided within the question it can be said that Excavate n' Fill's refund of the payment is a restitution. This term refers to when a court makes the defendant of a case (receiver of a contract) return his/her profit to the contrary party. Which is what Excavate n' Fill' is doing by returning the money that Fred paid to have his quarry filled, because they rescinded the contract.
