Apple ID Locked
I bought an iPhone 15 Pro Max newly. Apple ID is locked and I don't have access to the password and security questions and they are lost, that's why I bought Apple ID many years ago from someone who is not available now. When I call call-center of Apple company they told me there is no way. What should I do to use my new iPhone? I paid a lot of money for the iPhone and I need it.
I have the official invoice, box, and receipt and also I went to Apple store in Dubai Mall in person. Also, all information set on Apple ID is for me such as pictures, profile pictures, name, videos, games
I don't understand why there is no way to solve this problem
Please help me
