Whatsaap

Hello dear whatsapp, my whatsapp account was suddenly blocked and there was a warning "This account is not allowed to use whatsapp", I don't know what violation I made so that my whatsapp account was blocked, even though I didn't do anything that violated the policy at all whatsapp, I hope my whatsapp account can be restored again because my whatsapp account was blocked for no apparent reason, thank you.
