My Phone Number Was Used to Create an Unauthorized WhatsApp Account

I'm writing to inform you that someone has set up a WhatsApp account with my phone number without my knowledge or permission. Any conversations or phone calls made from this number are not from the owner. I am not the account holder and assume no responsibility. During the installation process, no verification code was sent to me, so the WhatsApp account was not created. We accept no responsibility for any damages incurred by this WhatsApp account, regardless of who owns it now or in the future. I urgently request that this account be closed. This has happened several times, and I've even changed my phone number, but the WhatsApp account is still open without my permission. Please assist me in resolving this matter as soon as possible.
