Ask WhatsApp support.

That is not an Apple product.

I don't know what "watsup" is – but if someone has managed to take over your account with that service, you will need to contact that service to get the matter resolved.

Apple does not control the accounts that you have with third-party Web sites and social media services – and the people you are talking to on this forum are fellow Apple users who have no control over this "watsup".
