I have same question as Tomycoco: how can I get my Comcast aerial cable put underground in my backyard instead of running about 95 feet through the air from the common utility pole (electric / telephone / cable) in my back yard to the eave of my roof (single story single family house)? I don't see any indication on Comcast website of where and how to start this process. Service address is in Merced CA.
I can reach out to your local line techs to see if this is something we can get taken care of for you. In order to assist you, please send me a private message verifying your first and last name, and the full account number or phone number associated with your services.
To send a private message click on my name "ComcastChe", then click send a message.
I was able to get the response I needed after posting to this board. Process not completed but I definitely got into contact with the person I needed to, hopefully works out for you too.
