Turn your monologue into a dialogue

My chief concern is getting a technician to my home. When trying to make an appointment I get dictated to when a technician will come, not even asked if it is suitable. I understand that technicians can only come during business hours, but also understand that I have work to tend to. Instead of telling me when a technician will come, ask me when is most suitable. Create a dialog.... Don't assume I have nothing better to do on a work day....
