Yes, I aslo find this problem. They are cheating us and there is no way for us to complaint it! They say for Chinese mobile it is free in 30 days but in fact one day after I bought the credit it's not free at all. And if we use phone 2 phone call, it's more expensive than normal rate. Maybe 2 or 3 times than normal rate. But they don't give any instructions on their website!
