Sigh. THAT just ruined my day. I guess I got screwed by them after all
I am here in Pembroke Pines and I got the same deal as you, but no charge for installation. I would urge you to call back and complain. They charged me for installation on accident. When I called to get it removed, I asked them for a service credit for my time and disappointment with their horrible billing.
BTW, my experience is that their billing in our area is a nightmare. Watch your first few bills like a hawk to ensure everything is right. This month I also found a $5 a month charge that was not supposed to be there. When I called I asked for a service credit again, or else I told them I would go back to satellite.
Use the retention department, they are easy to deal with and do not want to lose a recent subscriber.
