    CustomerUserLogin: customer user login
    DefaultServices: activate or deactivate default services

    Result: HASH -> returns a hash of key => service id, value => service name
            Name -> returns an array of user names
            ID   -> returns an array of user ids

    Example (get services of customer user):

    $ServiceObject->CustomerUserServiceMemberList(
        CustomerUserLogin => 'Test',
        Result            => 'HASH',
        DefaultServices   => 0,
    );

    Example (get customer user of service):

    $ServiceObject->CustomerUserServiceMemberList(
        ServiceID => $ID,
        Result    => 'HASH',
    );
