House being remodeled by contractors. No end date on contract?

[Joshua D.]

So are contractors have been a little shady lately . They are costing them selves money and the one came to me and said there not making anything. He hasnt been at the jobsite for 2 days left all there tools. He wont answer my calls just txts me back and i wanna get the project done. Hes doing other jobs with his brother who is also a contractor. Do i have the write to get on there asses like i need this done? The one brother did answer my call and said they been busy with a side job and trying to get done because guy is on there *** and im trying to get are place done. How do i got about handling this situation? Getting worried and nervous and concerned they are gonna walk out on me?
