Has Godaddy changed it terms?

I just got a whopping charge on my CC for full price domain renewals.

I wasn't notified in advance, they refuse to give me a coupon credit and worst of all NONE OF MY DOMAINS WERE ON AUTO RENEW WITH THEM EVER. After checking my GoDaddy account I find that now ALL my domains have been changed to auto renew.

Anyone else experience this with them?

What would you do in response?
