well it's possible to cheat achievements by either using a savegame of another user or by accident (glitch).
The latter happened to me once without knowing, but it's even reproducible. One of the FIFA games froze on me while I was offline and the next time I started my 360 it unlocked several online achievements.
That's technically cheating as the Xbox team can't know if that was an accident or not. They only see that I've won online achievements and don't have a time stamp for them.
Really the best thing would be waiting for a response or looking for other means of communication.
