If you've distributed a track through UnitedMasters, please reach out to us at firstname.lastname@example.org so that we can properly issue takedowns of your track(s). Once we issue takedowns, services will respond by removing the UnitedMasters distributed content from those stores.
It is important to note that if you’ve distributed music with us, your account will need to remain active for some time after you request takedowns so that we can continue to process any statements and payments owed to you for the periods your tracks were live.
If you haven't distributed any tracks, you can definitely delete your account. Head over to the UnitedMasters icon in the top left corner of your screen (where a navigation bar on the left hand side will pop up). Please click on “settings” and then scroll to the bottom. You should then be able to click on "Delete Account".
