Literally this exact same thing happened to a close friend of mine 1 month ago. All links to recovery information didn’t solve the issue and support seemed unable to do anything due to the email and phone number being changed. My suggestion is to back up all your photos as quickly as possible, there are tools on GitHub for this. If your account was private you will need to get someone already follows you to help.

Unfortunately it is very unlikely you will get your account back
