Hello,
I'm sorry that this happened to you. Unfortunately, nobody here can tell you or give information regarding why was your account terminated. If you will want to come back into the developer program later, you will need to make sure that you won't make the same mistake and explain the app review board the changes you will make in order this won't happen again.
What was the chronology of the steps you took? Did your app get rejected? Do you think you did something wrong, like purchasing reviews, or impersonating another app (same / similar icon, app name,..). Did you use any third-party libraries in your app, that could steal user data?
I hope you will find the issue and find success on the App Store in the future
Best of luck
