Create a strong password for your Apple ID, It is best if your password consists of eight or more characters and include upper and lowercase letters, and at least one number. You can also add extra characters and punctuation marks to make your password even stronger. 

Never provide your password, passcode, security questions, verification codes, recovery key or any other account security details to anyone else. Apple will never ask you for this information.

SS7 was an SMS vulnerability that was patched by cell service providers 6 years ago. You don’t send a tweet that way you go to Apples channel and post, they will respond or DM. If you are updated and not jailbroken you are not vulnerable if you are using strong passwords.

P.S. you might find Apple's Twitter site more to your liking.

If you have had 2-factor authorization for more than 2 weeks you cannot disable it. And you can change your phone number without turning off 2 factor authorization. Can you explain what SS7 is? And if you are running the latest version of iOS (as of this writing 15.4.1) and have not jailbroken your phone then no hacker is going to get to your account. And if you didn't give them your Apple ID password they have never gotten to your account.

No, just no. You are very confused and don’t know what you’re talking about. Two factor authentication prevents people from gaining access to your Apple ID because they need access to your phone, phone number, or other trusted devices. They can’t get access to that information unless you personally handed over to them. By reporting a spam text no one gets access either as I explained to you before.

Tweeting or emailing Tim Cook will only get your reply if it’s a true and worthwhile issue. You’re talking about something from years ago that is no loner relevant and have a general complaint because of your lack of understanding, they’re not gonna reply to you.

This is a customer to customer forum. Look at my reply below for how to actually contact Apple.

Can you answer my questions? And again, have you tried using the Apple Twitter site? But I would suggest if you hate Apple so much it is time for you to select a smartphone from a different company?
