If you've just registered with Teamer and can't find your Teampage, please contact your team organiser. Teampages are private and only those who have been invited to the Teampage by the organiser can gain access. Your team organiser may not have added you to the Teampage yet or they could have added you with contact details that do not match the details you used to register.
Also to delete your unwanted team, click into the team, choose "edit team" change the team name to "delete" and choose "update team". In the coming days when the system does its sweep the team will be deleted.
