As someone who had Comcast call to cancel on the day of my closing (two days before my scheduled install) because they didn't offer service to my house after all, I can sympathize.
They called you to cancel? You mean you close on the house, take a day off work to meet the installer? You didn't sit there for half a day waiting for them while CS rep claims they can't escalate until after the 4 hour appointment window? Then they say they have no idea why the installer did not show, can you hold please, then your disconnected after 20 mins on hold... fuck me I've been through this way too many times.
