WhatsApp Number Ban Preventing Verification For Six Months

I have been unable to use my WhatsApp account for about 6 months because my phone number has been banned and it cannot be verified on the app. I am using WhatsApp on an Android phone, and even though I follow the verification steps, my number is still not accepted. I have already contacted WhatsApp support about this problem, but despite my attempts, my number is still not verifying and my account remains inaccessible. I have not been given a clear solution or effective response so far. I kindly request that my phone number be reviewed, the unjust ban be removed if there is no valid reason, and my WhatsApp account be restored so that I can use the service again.
