I Cannot Access My Amazon UK Account Because My Phone Number Changed

I have an Amazon UK account registered with the email address smitjames****@gmail.com. Some time ago, I changed my phone number but forgot to update it on my Amazon account, and I no longer have access to the old phone. Since then, I have been unable to log in or verify my account because Amazon is still sending verification codes to the old number. My new phone number is 77776537**, and I would like my account to be verified using this number so that I can regain access. I have tried multiple times to resolve this through Amazon’s own channels but have not been successful so far. I kindly request that you contact me directly on my new phone number, 77776537**, to verify my identity and then update the phone number on my Amazon UK account accordingly, so that I can securely access and use my account again.
