I called yesterday to get my sewage fixed because it was backed up and it was an emergency and they booked me for the next day they called me 3x as a reminder that I had an appointment that day. I confirmed it and was told when they send a technician out it will be 45 mins to an hour so I sat and waited for a call comes 2:20pm I get a call that a technician will be on the way in 45 mins to an hour, as previously stated, so I wait the given time and than some and comes 3:45pm nobody arrived and I didn t receive a call saying the wait would be longer. I called them after waiting so long and asked what was going on they tried to reschedule me and apologized for the inconvenience, when they knew it was an emergency, I denied it as well as I heard from people in the background saying all the technicians went home. I am very upset with this company and will not use them!
