This could be tricky. Who has access to the first email account, of which the complained about email address was a secondary address? If the first account is still live and under the control of the account holder then the account holder can delete it it. VM can't and won't anyway.
If it is your old account and is now closed VM can help. Wait here for the VM team to pick u this thread.
But clarify the issue about account ownership first please to help the team.
