The telecommunications company may, within thirty days after the assessment is mailed, file written objections with the commission stating the grounds upon which it claims that the assessment is not reasonable. The commission shall within thirty days of receiving such objections hold a hearing and issue an order in accordance with its findings as to the proper amount to be assessed to the telecommunications company. The order may be appealed pursuant to chapter 1-26.
