Totally sleezy. No self respecting person would do this. That said, I've dealt with comcast before. After telling them I would cancel due to their arbitrary "end of promotion" I was redirected to their "loyalty department" which miraculously found another promotion for me that would prevent me from paying $80 a month for slow buffering internet.

If it even occured to them it might be sleezy, they'd rationalize that they do it to please their boss and keep their job, and that it's more important to them than being decent to a random stranger :/
