function plt_hide_storelinkformc_menus() {

	remove_menu_page('storelinkformc');
	//Hide "storelinkformc → storelinkformc".
	remove_submenu_page('storelinkformc', 'storelinkformc');
	//Hide "storelinkformc → Sync Roles".
	remove_submenu_page('storelinkformc', 'storelinkformc_sync_roles');

add_action('admin_menu', 'plt_hide_storelinkformc_menus', 11);
