Unsafe Intallation and Rude provider

Vodacom fibre (or their service provider) came to install, it took two days, but when it was done, the router was installed with cables coming over the edge of the counter, hanging cable and power cord. I contacted the installer on Saturday morning to advise him, he said that he would come after he was done, at the end of the day, he said he was busy, and could he come on Monday. Basic end to the story, Monday 5pm and he tells me he knocks off at 4pm, is rude to me on the phone. I cannot change the cable myself and relocate the router to a safe place because it is part of the router. Can vodacom please send an installer who is capable of installing the router properly in a safe place.
