This is what happened:
As you can see in here :
https://bitcointalk.org/index.php?topic=254488.40my account was blocked yesterday few hours after writing the code they give me.
Now, 24 hour later (must be some jocke with the site-name, which is not funny for me at all) they send my this:
I am representative of 24change.com.
Yesterday due to mistake of our manager we've sent you an 300 USD BTC-e code (Order: 23883), but we didn't already get your payment to our liqpay.com account. The fact is that payment was canceled by liqpay.com, and full amount will be refunded to your account within 6 business days. Due to co-operation with BTC-e.com administration your account was temporarily suspended, after you redeemed this code. Now to unlock your account you need to send us newly generated btc-e code with amount of: 300.0 USD BTCE. I hope you are a decent person and we'll recieve new BTC-e code from you soon.
Thank you for understanding.
Obviously everything was saved here so I have nothing to hide. As everyone can see I payed for a service in this place. They took my money. Didn't give me anything and once they gived to me they make my btc-e account block.
So VERY CAREFUL WITH BTC-E AND 24CHANGE!!
