My WhatsApp Account Hacked and Phone Number Changed

My WhatsApp account linked to the phone number 0033766644*** has been taken over without my consent and I have completely lost access to it. I live in France and this situation is causing me serious concern. A person I trusted gave me an email address and I opened it on my phone. While I was in the process of logging into my account, she changed the phone number associated with my WhatsApp account. After this change, the account was no longer under my control and I could not use my number on WhatsApp as before. I have contacted WhatsApp support about this issue, but the problem has still not been resolved and my account remains out of my control. I have not suffered any financial loss; my main concern is that my account and personal information are in someone else’s hands and could be abused. I request that my hacked WhatsApp account be secured, that access for the person who took over the account be blocked, and that the account be restored to my control as soon as possible. I would also like to be informed about the steps taken and what I should do to further protect my account and personal data.
