Ghost account login failure

I got redirected here from the support form response. See original message below.

Recently, because of a technical error, my work account philip.goto@pwn.nl got reset completely (same email but different account/id). I could login via Azure DevOps before, but since the reset I get the following error:

You can’t sign up because login ‘philip.goto@pwn.nl’ is already used by an existing user.

Could you delete my existing account so that I can sign up again, or make sure it will connect to the new instance of this account?
