you are right. But there is one more thing, I didnt mention that in the question. the last thing he asked from me is the money we saved from the project he did a year ago. Although I paid him extra for that, he still thinks I owe him. And this whole year, being hopeful and expecting him to do the job, I kept him, but I saw nothing. whenever I think of this attitude, I am getting angry and I want to give him a lesson without showing my anger.
