As I posted on MP, I took advantage of both the US & HA offers and had some miles credited to my accounts (US & HA). This proves that the deal was a legitimate deal and that sometime later EasyCGI determined that they didn't like the deal that they offered.

Clearly, at that point they have the right to stop offering the deal to people, however, they don't have the right to claim that the deal never existed for people that participated (and had credit cards charged) before they removed their offer.
