They even charge for the over the air free advertiser supported local broadcast tier and then they don't give you all that you are capable of receiving, only about half in my area. You see I live halfway between two City's that have different Network affiliates. This gives me a choice of 2 different network over air broadcasts for free, and cable charges me for the one that they provide me with!


And service? Who hasn't been told when requesting cable service ?We'll be there between 10am and 5pm effectively tying you up entire day. It never fails that they'll arrive just when I have to pop down to the corner market .
