Whenever any person is engaged in or is about to engage in the construction, operation, or acquisition of any telephone line, plant, or system without having secured a certificate of public convenience and necessity as required by Code Section 46-5-41, any interested person may file a complaint with the commission. The commission may, with or without notice, make its order requiring the person complained of to cease and desist from such construction, operation, or acquisition until the commission makes and files its decision on the complaint or until the further order of the commission. The commission may, after a hearing conducted after the giving of reasonable notice, make such order and prescribe such terms and conditions with respect thereto as are just and reasonable.
