“They sent a tech out on Thursday that didn't accomplish anything. I was disappointed. I called their dispatch and they put me in touch with a supervisor named Gabe. He offered to come that night at 9pm! I told him the next day would be fine. He showed up and diagnosed my problem. He even tolerated me watching and explained what he was doing.”
