First mailing whatsapp that my whatsapp tell me that server response is blocked.
After this, Whatsapp respond with the faq and if it not solve the problem, asking for Phone type, OS version and Whatsapp version.

I took the info from my friends phone and send it to Whatsapp.
After 2 weeks recieve final mail that if it hapen again i will blocked permanently.
Now i could register my number again.
