Finally after some correspondence with apple review team the update is accepted.
This was a tough one because explain technical details, i am not even involved in, not in your native language – might even have troubles in my mothers tongue – was uff.
The payment thing was the last on the list but the reviewer understood that i do not benefit from any transactions made “ingame” and thus ! yay 🙂
Now back to the real work, updating features and fixing bugs.
