If Comcast sues you for payment then you go to court (or more likely to an arbiter chosen by Comcast since that's what you agreed to in your contract) where evidence matters.
But instead of that, Comcast simply reports you to the credit bureaus for non-payment. The law gives them immunity for doing so -- even if they submitted intentionally false information for malicious reasons, you can't sue them for libel. And you credit score affects your ability to function in US society: it is used for all granting of credit, for deciding whether to allow you to open a checking account, for deciding whether to hire you at a job -- it is so significant that you are forced to care. You can open a dispute of facts with the credit reporting agencies, but be prepared to spend large amounts of time doing so.
Really!
