Don’t have access to my trusted phone number or password

I don’t recognize the trusted phone number and have no way to access it to reset my password which I also can’t remember, I’m worried my account was possibly hacked, after talking to Apple support I was told they couldn’t take the phone number off the account even though they said they believe I’m the owner of the account. How can I reset my password and get access to my account without the number or password or key, I can awnser the security questions if given the chance
