Please don't use their service! It's terrible! They don't even deserve a star. I had an appointment with them to fix gas leak from 2pm to 5pm. But nobody showed up. I called them and they said a technician will call me back shortly. I had to wait for another hour but nobody call me! I called them again and they kept saying a technician will call you. Seriously?? I waited for another 30 min and finally they called me back. All that technician told me was they have to reschedule my appointment to 3 days later. OMG... They don't even respect their customer at all. So if you consider to call them for a service, please DO NOT!
