In case a person refuses to obey such subpoena the commissioner or his representative may invoke the aid of any circuit court in order that the testimony or evidence be produced. Upon proper showing, such court shall issue a subpoena or order requiring such persons to appear before the commissioner or his representative and produce all evidence and give all testimony touching the matter in question.

A person failing to obey such order may be punished by such court as for contempt.
