WhatsApp Cannot Be Used On This Account Error

For a whole week now, I've been unable to log into my WhatsApp account due to a "This account cannot be used" warning. I've sent numerous emails, but there's no solution in sight. I'm fed up with the endless "Help" messages. I'm at my wit's end, facing a nerve-wracking crisis, and there's no one to talk to. I need a resolution urgently. They've left me feeling genuinely victimized. I even got a new number, shared it with everyone, and then got blocked. Apparently, I'm considered suspicious. What a shame, what a shame on you. You've truly left me in shambles.
