C&c custom cabinets and granite

Chris came out promptly and friendly to close the deal on our granite work for our large kitchen. He was highly recommended by a friend of ours, and seemed to know his stuff. He came out, took measurements, took my two sinks (large farmhouse and undermount for laundry room) and assured me it would be installed promptly. 
He set an appointment to install on March 4, Friday afternoon, He failed to make that appointment, and set it for the following Monday. He also broke that appointment, as well as Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday. We finally had enough and decided to write this job off. He called and promised that he would arrive Monday morning, 10AM. Monday came, he texted to tell me that he wasnt going to make it.
We were renting a place to stay during this, and since we have a 7 month old baby the one thing we needed installed was a sink so we could wash her bottles. We moved in over the weekend with the fantasy that he would live up to his word. Which didnt happen. He has every excuse in the book, but its clear that hes having business troubles; his partner quit, he has no help, and just canat do it alone. We paid him $3324 up front, as well as over $6k for material. He is refusing to release the material so we are now out all of our money.
