Rotten Coleslaw

I bought a family meal with the 3 free sides, got home and sat down to eat, my 7 year old almost vomited in the plate, I tasted the coleslaw and it was the most horrible, rotten taste, and bad smell. On checking the expiry date it was expired. We packed up the meal and took it back, one of the front staff confiscated the coleslaw quickly then returned to ask now what must she do. I asked her for the coleslaw because I would like to show the manager and she had the worst attitude I have ever seen saying that she threw it in the bin. I then showed the manager a picture of the coleslaw with the expiry date on. The manager instructed the rude staff member to bring the coleslaw, the rude woman kept clicking her tongue and saying 'haai these people' the opened the lid and agreed that it is smelling really bad and noticed the expiry date. Thank you very much KFC for spoiling another meal! If we spend our money on takeaways we expect to get home and enjoy, not to get sick and drive up and down every time. Traderoute KFC is not keeping up 2 standards. I finally got a refund after a long wait and being bul**** by the rude staff
