Very bad sevice

Rang for service on plazma tv,technician came and repaired fault in tv, but left cables hanging down outside of wall did not bother to put them back behind wall as they were.Also just left me with no foxtel or dvd player working and just said to get someone else in to fix them,which i might add were working absolutely perfectly before technichion came' Had to get someone else in to fix his mess and it then cost me an extra $480. Samsung plazma was still under warranty and this is how they treat you.
