2nd Generation General Contracting

I hired 2nd Generation General Contracting to replace my deck and had a terrible experience. The crew pulled up my original deck and then would leave for a couple of days to complete another project for a different customer, come back, do a little more work and then leave for a few more days to continue working for another customer. When they would show up, they complained about not having enough money for materials and ask that I pay more towards the final amount. I was told it would take approximately two weeks to be completed and six months later, it has not. They abandoned the job halfway through and stop returning my calls. I have had to hired two other companies to try and get this project completed, but they left it in such bad shape that new contractors are afraid to complete the project.
