how to use config data in seeder

The use statement with non-compound name 'Config' has no effect. My code constants file:

return [
        'sale_type' => '1',
        'payment' => '2',
        'bill_type' => '3',
        'tax_fixation' => '4',
    ]

Seeder File:

$sale_type =[
            ['text' => 'Order Delivery Sale', 'type_id' => Config::get('sales.sale_type')],
            ['text' => 'Direct Sale', 'type_id' => Config::get('sales.sale_type')], 
            ['text' => 'Advance Sale','type_id' => Config::get('sales.sale_type')],
            ['text' => 'Promotional Sale', 'type_id' => Config::get('sales.sale_type')],
            ['text' => 'Online Sale', 'type_id' => Config::get('sales.sale_type')]
        ];
        DB::table('list_type_selection')->insert( 
            $sale_type
);
