I booked an appointment for 11am. At noon I called Arpi's to ask when my repair man was showing up, I got the response that my appointment had been bumped to noon and that my window was now noon to 2. #1, if you are going to change an appointment time, you should inform the person that booked it. That's why I gave you my contact info. #2 I should have been informed of the 2 hour booking window when I made the appointment. Also $425 yo replace a pilot light? Is it made of diamonds?
