Disappointed in our last service call. Technician...

Disappointed in our last service call. Technician quoted us a price to install smoke detectors and a light fixture in our bathroom. When he came out my wife was the only one home and he increased the price by $135 for the light fixture and he said it wasn't in the original proposal. He also installed only 5 out of 6 smoke detectors because one was tied to the security system. This is fine however he didn't reduce the price by one smoke detector. I feel he was taking advantage of my wife, because he had the opportunity. Very unprofessional for TLC to do that. I understand we will pay a little more for the value that TLC provides but they should not take advantage of people.
