HOw do I file a suit on a company that I paid for kitchen remodeling and all cabinets have cracks and granite is separated?

I contracted a company to have new kitche3n cabinets and granite countertops. The cabinets have cracks or "hair line cracks" in their words on all doors and drawers, the granite counter top has a piece that was added to make up for the length, where the two granite slabs meet at the sink it is completely separated . I have contacted both the contractor and also the manufacturer no one is doing anything about this issue. The Manufacturers respond is that painted cabinets always have cracks because the wood expands.. They would replace the parts but does not mean it was going to resolve the issue. Because They are still painted cabinets. The company I contracted never said anything about those cabinets would have cracks and still not resolving the other issue with the granite counter top either. It has been 6 months now and no one is doing nothing. I paid $13,000.00 and I am not happy with my kitchen and the outcome..
