Over Charging Ripping people off

I was living in a smaller place and setup directtv. I moved to a bigger house and got my service transferred. Now that I have more rooms I wanted more wireless boxes for my cable services. I called 4 different times and still being told it's $99 to hook up a hdmi cord and plug the box in my electricity outlet for each room and it's $8 a month for each additional box. I first asked when they was coming out to transfer my service to hook up extra boxes since the technician gotta come out to hook up boxes just pull out 3 more boxes and hook them all up also. But no I keep getting told i gotta pay a extra $99 each room hookup. I'm so disappointed I. Directtv I will never use yall services again once my contract up or someone willing to buy out my contract I will be done with directtv yall is ripping ppl off to mess up there credit score. This is not a good company.
