So basically you got banned by PSN. It also sounds like a console ban. What you need to do is buy a new console id from someone. I recommend UngodlyJames (YouTuber)
You must login or register to view this content.
On that page it also has a link on how to change your CID when you buy it. This will get your console unbanned but not your account. You can not unban your account at all. Also next time be more careful and clear syscalls, and psnpatch, as well psninja just for precautions.
