Alright, you can get that process started here.
I've asked a Comcast employee to help you. You should expect a reply in this thread.
Hi Pompanosix -- I can help you start a damage claim. Please send me a PM with your name, full service address, and either phone number or account number for authentication. Please include a description of the damage you're wanting to claim and I will get this submitted for you.
Click my name (ComcastZach) and click Private Message Me.
