Appliance Service People The

My dishwasher stopped working. The technician came and he found that there is no power. We checked the switch board and it was off. We turned it on and it started working. when I called them they told me that the charge will be $45. If need labor and parts they will charge accordingly. He charged $20 extra for the labor. When I asked him to explain why he said rudely that " next time call someone else not me". I promised to do that!
