KFC RAISETHORPE - RAW / UNDERCOOKED CHICKEN

Ordered a meal via the KFC delivery app only to start having supper and find out that the chicken was raw and that only the part was under the skin was cooked. Because we had already eaten portions of the chicken before finding out it was raw we all became sick. Because we have a medical personnel in our family we were given meds to control the side effects of food poisoning. When I filed a complaint against the store they insisted nothing can be done without a medical report. This is madness. They are not even apologetic. They are rude and they all ask the same questions but with no results. I asked for a refund of the meal and nothing can be done about it. This is pathetic behaviour on the part of the store manager. In our case it was food poisoning....what are they going to do if someone ends up with salmonella from consuming raw / undercooked chicken??? The quality of the food is poor as is the service they provide.
