WhatsApp Keeps Banning Accounts on Huawei Y9 2019 – Official App Only

I am using a Huawei Y9 2019 (model JKM-LX1) and for the last two months I have been experiencing constant bans on WhatsApp. During this period, more than ten times my accounts were banned, and now two of my numbers have been permanently banned, while a third number is being frequently banned on the same device. I have not used any unofficial or modified WhatsApp applications such as GBWhatsApp or WhatsApp Plus, and I have not used these numbers on any other device. I only used the official WhatsApp application from the Play Store on my Huawei Y9 2019. I have not purchased any special services or virtual numbers; they are normal SIM numbers. Despite this, my accounts keep getting banned, which makes me think that my device itself may have been incorrectly flagged by your systems. Until now, I have only used the in‑app review option and have not been able to get a clear explanation about the reason for these bans. I kindly request that you permanently unban my WhatsApp accounts and numbers that are linked to my Huawei Y9 2019 device and that you investigate in detail why my device or numbers have been flagged. I also request a clear written explanation of the exact reason for these bans so that I can avoid any similar situation in the future.
