Our landlords use Service America as they live out of state. On several occasions Service America has either not shown up or has arrived hours after promised with no calls regarding being late. I took the day off AGAIN only to find the technician is running hours late. I called 3 times today to confirm the appointment and no one took the initiative to contact the technician to help identify an accurate time of arrival. I hate this service! I would much rather call a local company directly then go through this service.
