<a href="<?php echo esc_url( wc_get_page_permalink( 'myaccount' ) ); ?>" class="button pay"><?php _e( 'My account', 'woocommerce' ); ?></a>
<?php endif; ?>
</p>
<?php else : ?>
<p class="woocommerce-notice woocommerce-notice--success woocommerce-thankyou-order-received"><?php echo apply_filters( 'woocommerce_thankyou_order_received_text', __( 'Thank you. Your order has been received.', 'woocommerce' ), $order ); ?></p>
