Pure Green Construction

It started out 2 weeks ago last Friday. We sat down and wrote up a proposal. He called because I was out of town, and he said that the roof was not near code, and it didn?t have legal pitch. He never put it down in writing, but he said he would do all of the work for $25000. He was going to do a basic complete overhaul of the roof. That Friday we gave him, $3000 to start the work, and they took some roofing off and cut a hole in the roof, but they didn?t cover it up. It rained that night, and it damaged the drywall in my dining room. On Saturday, they were working on the roof, and on Monday, he said it was going to cost more than he thought because he needed to re-frame the entire roof, so we gave him another $10,000 more. The following Friday, He then asked me if he could get $7000 to make payroll. Then, a week ago last Monday, he told me that he?d under bid the job by $3500. At this point, he asked me for additional money. I told him I had no more money left to give. On Thursday, they finally got the tar paper down on the roof, and that was the last I?ve seen of them. I?d already given him $20,000, so I told him no more money until it was finished. I?ve been pricing the materials at Home Depot, and he is no where near this amount in materials. He has told me different stories about the cost of the shingles and where he needs to pick them up. Yesterday, I called, and they told me they were going to be here today to finish up the job, and now I can only get their voicemail, no matter what number I call. He gave me a 3 week deadline, and the deadline isn?t here until Friday, however I?m concerned with the fact that they are unreachable, and they are not showing up.
