"They finished about half of the work. It should have been completed the first week in May. The contractor said he suddenly had back problems so I gave them time on that. In the mean time he has given me a number of excuses and is not returning my phone calls now. I still have more than half of the work that sitill needs to be done and am getting no response from him.
Since he has recovered from his medical problem, he has come out and finished the project. He had a genuine reason not to finish and I have completely forgiven him. He did a nice job. "
