Something like a disconnect charge, that Comcast can cancel a service but they are going to still charge you for it, should be on the document you sign, not buried in a link on a web page.
Plus, the link that is on the contract you sign, doesn't even have the 60 text on it. That is another document that is linked to from that link. I'm not even sure a link to a page that then has another link to a totally different document is really part of a legal contract.
The fact is, they just need to be honest with people and not hide the fact that they are going to continue to take your money 60 days after you canceled. There just is no reason for it and I'm amazed it is legal.
Imagine if you switched electric companies and the previous company kept on billing you? Never would happen. How is this allowed to?
