Wp_Schedule_Event every few minutes doesn't work

Question

I wrote the folowing timer in my function.php file. It should be called every certain time (3 minutes) but it doesn't work at all.

function myprefix_custom_cron_schedule( $schedules ) {

 $schedules['every_three_minutes'] = array(
      'interval' => 180, 
      'display'  => __( 'Every 3 minutes' ),
  );
  return $schedules;
}
add_filter( 'cron_schedules', 'myprefix_custom_cron_schedule' );

if ( ! wp_next_scheduled( 'myprefix_cron_hook' ) ) {
  wp_schedule_event( time(), 'every_three_minutes', 'myprefix_cron_hook' );
}

add_action( 'myprefix_cron_hook', 'do_anything' );

and here is my function:

function do_anything($user_id) {
  update_user_meta( $user_id, 'alg_wc_ev_is_activated', '0' );
  wp_redirect(  wc_get_page_permalink( 'myaccount' ) );
  exit();
}

I don't know, why it doesn't work. Am I missing something in code?
