If the service has already been activated at your house in your name, then you should be able to pick up the boxes and install them yourself.
reply to wizkid6 Going to install.charter.com only installs/provisions HSI equipment if i'm not mistaken.
Can't I just go up to the office, pick it up, and go to install.charter.com after the office adds it to my account?
reply to wizkid6 I activated my own HSI with Charter once TV service had been installed. At that time I had my own modem, and all cable outlets had been activated.
