Man. I'm also a victim of this. I still don't know where all the policy change communications came in? If it was just on their website, I wouldn't have seen it, as I've been neglecting the account.
I also lost a lot of points, around 200,000 or so. I'll call them, but I already sent an email. I'll wait to see what they say. If it's a negative, I'll try to speak with a supervisor on the phone.
