I need my lawyer to perform but he is slack how can i boost his performance?

I know my court date but my lawyer is so slack that he is still waiting to tell me my court date. all he needs to do is call the courthouse like I did to find out, but acts like he's waiting on some letter from the court verifying court date. I dont know whats up but I am very pissed. he has been a great help in the past but its like he has run out of gas all of the sudden right in the middle of my case .what to do?
