WooCommerce - Remove automaticly added membership product if user remove regular product from cart

I managed to add a product if a user is the first buyer. But when what I want to achieve is when a user deletes that product, automatically gift or membership product will be deleted. I was using woocommerce_cart_item_removed, but with no luck. Probably I'm missing something but I don't know what. If someone wants to help me, I will be more then thankful

    $bought = false;

    if(!get_current_user_id()) {
        return false;
    }

    // Get all customer orders
    $customer_orders = get_posts( array(
        'numberposts' => -1,
        'meta_key'    => '_customer_user',
        'meta_value'  => get_current_user_id(),

    ) );

    // Going through each current customer orders
    foreach ( $customer_orders as $customer_order ) {
        $count++;
    }

    // return "true" when customer has already one order
    if ( $count > 0 ) {
        $bought = true;
    }
    return $bought;

MY SOLUTION

add_action( 'template_redirect', 'remove_membership_from_cart', 10, 2 );
function remove_membership_from_cart() {
    $free_product_id = 14275;
    if ( sizeof( WC()->cart->get_cart() ) === 1 ) {
        foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
            $_product = $values['data'];
            if ( $_product->get_id() == $free_product_id )
                $found = true;
                $cartId = WC()->cart->generate_cart_id( $free_product_id );
                $cartItemKey = WC()->cart->find_product_in_cart( $cartId );
                WC()->cart->remove_cart_item( $cartItemKey );
        }
    }
