According to this document : https://codex.wordpress.org/Class_Reference/wpdb

you must change your code to this:

global $wpdb;
$wpdb->insert(
  'wp_test',
  array(
    'orderID' => $_GET['orderID'],
    'amount' => $_GET['amount'],
    'acceptance' => $_GET['ACCEPTANCE'],
    'status' => $_GET['STATUS'],
  ),
  array( '%d', '%d', '%s','%s' )

);
