I tried to open a new account and I am banned for no reason

I want to sign up and connect via my Github account. I have not used the site at all, the web development course that I am using wants us to use Netlify to deploy our projects but I am unable to log in.

I verified access but when I try to log in it says “Authentication Error Authenticating failed due to the following error: We already have a registered user with this email address. Log in to connect your GitHub account.”
I have logged in and out of my Github and tried logging here and its not working.

Then I received the following email:
"We regret to inform you that your account has been flagged due to increased potential for fraudulent behavior. As a result, we are unable to enable your account. We understand that you may have questions regarding the ban; however, please note that we will not be able to provide further review or additional reasoning for this decision.

We appreciate your interest in our services, and while we understand this may be disappointing news, we take the security and integrity of our platform very seriously. Our Fraud and Abuse Team has thoroughly reviewed the situation, and based on their assessment, the decision to disable your account has been made. We value your understanding and cooperation.

Thank you,
The Netlify Fraud and Abuse Team"

I am not sure what to do now because I cannot complete my course. I am also not sure how to prove that I have not done any fraudulent activity especially since I have not used Netlify previously. I am confused as to why I am banned when I have never used your service or done anything to prove that I have been involved in fraudulent activity

@Ash See this thread:

Netlify may not respond to your ban, so you may want to try using another provider.

The usual solution for the authentication issue is the following steps.

  1. Login to Netlify using the email address and password only. If you do not have a password configured, you can add one by using the password reset form: Netlify App
  2. Once logged into Netlify with the email address and password, change the GitHub account associated with this email address here: Netlify App
  3. Log out of Netlify.

Once this is done, you should be able to log into Netlify using GitHub or the email address. Both methods of login should work now.
