Yet another question regarding how to delete my account

Hi there,
How to delete my account? I have connected my account with GitHub 9 months ago and start building a project. Unfortunately, I had to stop it right after and delete my GitHub account. Now I have created a new GitHub account (same username) and ready to start from scratch (building with CircleCi 2.0) but when I try to connect my new project I still see the old one and the build does not work.

Is there a way to complete delete my account and start from scratch reconnecting with GitHub?

Thank you.

It actually works now so I guess I can consider the issue solved.
