I managed to cancel my dad's after he died. They STILL tried to upsell me! One of my favorite phrases ever uttered: "He's dead, you asshole, he doesn't need more channels!" And that actually did it. Felt sorry for the salesperson, who didn't have much of a choice in the matter...
Surely by making it difficult to cancel they’re really just making it easier for people to get discounts. If I were a Comcast customer I’d be calling up to cancel every few months.
To be fair, internets would have been equally outraged if there wasn't such requirement, because sure as hell somebody would have found an exploit and cancelled a bunch of account, just for funzies
