Camelot Marble & Granite

I hired Dan to do my counters at the beginning of November 2017. He came out and did about half of the work, but has been paid more than half of the total cost. Since then, he has no showed appointments 4 or 5 times, when he did show up for one appointment, it was 2-3 hours late. He has been extremely difficult to get ahold of, never answering his phone and rarely calling back, and when he does, he is very aggressive. Each time he was supposed to come out, I've had a plumber ready to hook the new sink up, only to have reschedule. I have not heard from Dan in 2 or 3 months now, and I am still waiting for my countertops to be finished.
