They are not required to notify you of anything.
They ARE required to notify you. As I pointed out, they simply choose to do it at the point when you sign up. There's a handy little link on the website that clearly tells new customers that the advertised promo prices will go up after the promo period.
That's it, their obligation is done. I was responding to techs, who was being an ignorant dumbass trying to imply he was NEVER notified that it was promotional pricing and the price would change.
