KFC complaint: Missing items poor service

I visited your drive through on the 6421 at around 6.15 pm the female at the kiosk was a bit sharp when I asked when the zinger burgers would be ready after she said they had none at the minute when in fact they had none at all, I then ordered my food and got home, the food was packed disgracefully to the point the burgers had been put in side ways and had come out of the box and were in the bottom of the bag, they had missed out the 2 sides of gravy I had paid for, I paid on the card and didn’t get a receipt, I tried to ring the local restaurant to explain the missing items, the food was just about warm enough to eat so short of going back out to the place we were stuck, cctv and my debit card will no doubt time date and proof of purchase I did try to do this on the KFC official web site but after 4 or 5 times of entering the details all correctly I got fed up and googled why I couldn’t get through and here we are.I know it’s trying times and you are providing a service me and my wife are also key workers who have worked all through and felt like a treat for ourselves
