Unable to Set Up WhatsApp Account Due to Missing SMS Verification

I am unable to set up my WhatsApp account, even though the phone number and device are mine. When I try to log in, I don’t receive the SMS verification code required to complete the setup. Instead, I encounter a persistent "Contact Us" error message.

This situation is incredibly frustrating, as it prevents me from communicating with anyone via WhatsApp, which is my primary mode of staying in touch. I’ve tried multiple times with no success and urgently need this issue resolved. WhatsApp support, please help me regain access to my account immediately. Reliable communication is crucial, and this disruption has caused me significant inconvenience.
