This should have happened due to the busy schedule with the Takeaway or Restaurants. If you come across such cases, please contact the Takeaway immediately so they can ensure you get the missing/wrong item delivered shortly, or sometimes the Takeaway might try to get this sorted on the next order. But before contacting the Takeaway, please make sure you check your order details sometimes you might intend to order an item and you might have missed or placed different items while ordering. So, please make sure to check the order details on your Order History page and contact the Takeaway using the number mentioned on the View Info.
