Help Help me regain control of my iPhone

[owin tanphat]

I have an Apple account on my iPhone 11 pro. Because my daughter didn't know, she mistakenly pressed the delete account button on the Apple website without saving the recovery number. I didn't know that, so I ran the software again for my iPhone. stuck at the activation screen. When I tried to log in to my account, it said the account no longer existed even though it was still on my iPhone. The username, phone number and password belonged to the account. It's me, but now I'm locked, it's so funny. Do you have any way to help me solve it, thank you very much. I contacted Apple support and they said they wouldn't accept it because my iPhone is a genuine product. Return the warranty and buy it back. Thank you for viewing my news
