First thing I'd do is call your attorney and speak to him personally and tell him you know that he's lied to you about the reasons for the adjournments and ask for a straight answer as to what is going on. If the answers are not satisfactory, then I suggest you see about finding a new attorney and filing a complaint with the state office that disciplines lawyers for misconduct. You don't want to move forward on a case with a lawyer representing you that you do not trust.
Also, why are you not present at the jury selection? In most cases, the client should be there for the trial, and that includes picking the jury.
