Request To Review And Unban WhatsApp Account

My WhatsApp account linked to the phone number +923118279*** has been banned since 4.12.2025 without any explanation. I did not receive any in‑app notification or email from WhatsApp informing me about the reason for this ban. I have never used any unofficial or modified versions of WhatsApp such as GB WhatsApp, FM WhatsApp or similar applications on this number, and to the best of my knowledge I have not violated WhatsApp’s terms of service. Despite waiting for several days, my account is still not accessible, and I have not been given any information about what has caused this situation. I may have logged in from another device or via WhatsApp Web in the past, but I do not clearly remember the exact usage before the ban. I kindly request that you review my account in detail, clearly inform me of the specific reason for the ban, and if there is no concrete violation, urgently unban and reactivate my WhatsApp account.
