add_action( 'woocommerce_before_thankyou', 'gurmewoo_failed_orders_wc_status' );
 
function gurmewoo_failed_orders_wc_status( $order_id ) {
 
   // GET ORDER FROM ORDER ID @ THANK YOU PAGE
   $order = wc_get_order( $order_id );
 
   // EXIT IF ORDER HAS NOT FAILED
   if ( ! $order->has_status( 'failed' ) ) return;
 
   // LOAD THE WC LOGGER
   $logger = wc_get_logger();
    
   // LOG THE FAILED ORDER TO CUSTOM "failed-orders" LOG
   $logger->info( wc_print_r( $order, true ), array( 'source' => 'failed-orders' ) );
 
}

function gurmewoo_log_price_changes_wc_status( $product_id, $product ) {
 
   // GET PRODUCT PRICE
