Contractor won't provide receipts

[Sabriya Simmons]

Large basement reno with materials and labor seperate. Contractor requested home depot reloadable gift card loaded with my money to keep and buy all supplies and now will not provide receipts for those purchases. I'm unable to obtain receipts from home depot. Contractor is owed 3k and refuses to provide receipts for materials. Do I have any recourse? Contract is vague and has final payment being paid prior to final inspection.
