WhatsApp Blackmail Complaint Private Photos Used for Threats

I am writing to report a very serious case of threats and blackmail that I am experiencing through WhatsApp and to request urgent action regarding this issue. A person using the WhatsApp number +91 97985 037** threatened me after a video call. During the video call, this person recorded the call without my consent. Afterwards, they used the recording, which contains my private photos and videos, to threaten me. They are pressuring me to send more private content and saying that if I refuse or block them, they will spread my photos and videos. Because of these threats, I have not been able to block the number, as the person clearly says they will distribute my private images if I do so. I have already reported this WhatsApp account through the in-app reporting tools, but the number can still contact me, and the threatening messages have continued, which makes me feel unsafe and under constant stress. I request that the WhatsApp account associated with the number +91 97985 037** be permanently blocked due to blackmail and threats involving private images. In addition, I request that this user receive a clear warning or any other appropriate sanction for this behaviour, so that such actions are not repeated against other users. If possible, I also request your support to prevent my photos and videos from being shared through WhatsApp or to remove any content that may already have been shared. I want to continue using WhatsApp safely, and I kindly ask you to urgently review this situation and take the necessary actions. Thank you in advance for your support.
