I need to delete my playstation account or need to know how to switch the email, but the problem is a have over $50 dollars in downloads and I want to keep all my achievements on PSN ie: levels prestiges stuff like that. Is there anyway to keep all of this and and switch my email or make a new account
I'll comment anyway.
You can change your email in account management either on your console or here.
PSN Accounts can't be deleted but you can have it banned by asking customer support and proving your identity.
