Degraded service

On the 24 /10/2019 went to KfC Goodwood went did my purchase through drive through around 9pm ... I bought 5 peace meal I was so disappointed firstly with the that took long then I get home I find that the meal has two wings and 3 other pieces I really felt so insulted and disrespected. What kind of service must one pay for to get what you actually purchased. If this is not attended I will never buy from KFC
