Moving to a new house. Install scheduled for Thursday. If they show up should I go ahead? Already have basic cable. Any thoughts? Yes I know I'm only out $1. Tried to upgrade my cable order thru comcast to add 3 high def. boxes. Comcast computers would only let me add 1 HD box to my original order. I'll have to add the others on a new order, different date. Maybe voom cust. service isn't so bad after all?
