How can I delete my apple account? I opened it to submit my podcast only, but this crap doesn't work!

See the documents below. Apple recommends deactivation rather than deletion. But, of course, the choice is yours.

“While your request is being processed, you can contact Apple Support with the unique alphanumeric access code you received, and we’ll help you cancel your request. After your account is deleted, Apple can't cancel the request, reopen your account, or restore your data.”

How to deactivate your Apple ID account  https://support.apple.com/en-us/HT208503

If you request account deactivation, you'll receive a unique alphanumeric access code. When you're ready to reactivate your Apple ID, contact Apple Support, provide your access code, and we’ll help you reactivate your account. If you lose this code, we won't be able to help reactivate your account." 

All purchases made using an Apple ID are tied to the ID. Delete the ID and you will need to download them using your new ID. There have been posts by people who have contacted Apple Support and they were told that if you delete an ID associated with an email address, you can never reuse the email address for an Apple ID.   Make sure you sign out from the places in the 3rd link before deleting the ID.

Did you actually manage to submit your podcast? If you then delete your Apple ID you won't be able to access Podcasts Connect for statistics or troubleshooting. Indeed I'm not sure what happens to a podcast whose Apple ID has been deleted (since this facility was only introduced recently - before that you simply couldn't delete an ID).

If you are having trouble of any sort with your podcast, including submitting it, the best place to ask is in the Producing Podcasts forum, where I can try to help you - though please post your feed URL and you Store page if you have one, without which one obviously can't help. And if you get any error messages please quote them.
