Is it malpractice if a defendant in a civil lawsuit asks their attorney to the request and never gets it done?

My attorney agreed to get several people to testify on my behalf and never got it done until it was too late. My case has weakened because of his negligence and now I have no one. He also sent me to the courthouse to request a copy of a deposition I never received. The judge's sect, asked if I had a lawyer and irritated with me for asking. Another lawyer told me that my lawyer made me look weird.
