WhatsApp Locked My Account and Forced a Phone Number Change

I am writing to report a problem I am experiencing with my WhatsApp account. Recently, when I tried to use my account, I was asked to change my phone number to continue, even though I want to keep using my current number. Because of this, I cannot use my WhatsApp account as before, and this is causing me difficulties in my communication. I have already contacted WhatsApp support by email about this issue, but I still do not have a solution, and my account is not accessible on my current number. I urgently request that my WhatsApp account be reactivated and fully restored on my current phone number without requiring any number change, and that I be informed clearly about the reason for this situation, and that this is resolved as soon as possible.
