Adventures in 'Comcast' Land...Getting Connected and Customer Service

To save time and a trip to their satellite office, my wife set up the installation of Internet Service with Comcast online for our new digs.
Things obviously work since I am writing this piece from my home office.

Let me mention 4 things they could improve on.
First: If you mention that your online session to order service will be followed by an e-mail do so (did not happen).
Second: When offering a time slot and after having your customer confirm that it works for them do show up on that day and time (it failed and we had to reschedule).
