Phonce Call regarding Icloud Hacked

It is not legitimate.

Apple does not make such calls.

All such calls are scams from criminals attempting to steal your personal and financial information. The callers will often use number spoofing to pretend they are calling from a legitimate business. The correct course of action is to hang up on them, repeatedly if needed.

The call is not "legitimate." Apple will never "cold call" a customer with that, or any other information. You can safely ignore the call/block the number.
