Failed To Use WhatsApp On My New Samsung Galaxy A73 Phone

I recently purchased a new Samsung Galaxy A73 5G and today, when I tried to install and use WhatsApp Business, I could not complete the verification process. During verification, an on‑screen message appears stating that I am not using the official WhatsApp application and asking me to install the official app, even though I am already trying to use the official WhatsApp Business version from different sources. I attempted several times, downloading WhatsApp Business from different websites and repeating the verification steps, but every time I received the same error and my account could not be verified. Because of this, I am currently unable to use WhatsApp Business on my new Samsung Galaxy A73 5G at all. I request that this verification issue be resolved so that I can use WhatsApp Business normally on my device. If the problem cannot be fixed and I remain unable to verify and use the application, I also expect a suitable refund or compensation for this situation.
