Here a screenshot of the mail, i receved it today at 19:47.
I used their wallet mined there and bought hashing power.

If the mail is not from them then the hacker must have stolen more than just BTC, user information too. otherwise how would someone get my mail adress?

Maybe the difference is that I didn't buy any hashing power. Just mining with my own hardware.

OK, let's hope for the best.
