Comcast said more then once what it cost for a comcast worker to come to my house to put in a new cable box! The cable box is the X1 and you install it just like the rest of the boxes they mail to you to install yourself! The price was $39.99 to install their equipment! I checked my bill and they have a $20.00 fee that I asked about and the $39.99 fee! No one could tell me what the $20.00 fee is for! They put things on your bill like other charges and don't explain what the charges are! On top of that they bill customers in advance! I can't watch tv in advance! That needs to be stoped! When they bill me in advance my bill is over $300 or more!!!
