What is the issue with phone number or nationality. Are you not able to see your nationality in there registration portal or is the phone number you have not corresponding?

Or you have a winning that you couldn't withdraw?

Anyway you need to do more clearification. However, I don't think this board is the right place you can ask your question. You can go here https://bitcointalk.org/index.php?board=83.0 for more clearification.
