Query regarding state criminal case

I am accused in a criminal case and i have charged for section 147/323/307/452 IPC by the session court. This case is on the stage of prosecution evidence since two years but the complainant/pw1 is not coming in the court for the testimony. multiple times Summons and bailable warrants have been served upon her and multiple times the councel of complainant have taken adjournment on which the learned court have imposed fine on that adjournment. after how much time the trial court can close the evidence of the case if the complainant still not come to the court for testimony?
