My Whatsapp Account Have Been Hacked

My WhatsApp account linked to the number +233 55 657 70** has been hacked. About two weeks ago, I was logged out of my WhatsApp on my Android phone, and since then, the attacker has been using my account to send messages to my contacts without my permission. I have not been able to take any recovery steps yet, as I do not know how to contact WhatsApp support or correctly report the issue through the app. While this continues, my personal data and my reputation with my contacts are at risk, because they may receive fraudulent or misleading messages that appear to be from me. I request that my WhatsApp account be urgently secured and my access restored. I also ask that any unauthorized activity on my account over the past two weeks be investigated and that any suspicious sessions or devices be logged out so I can safely use my account again.
