Not receiving goods

This is now the third time that I've paid for food, however when I get home, only half of what I paid for is in my take away bag. Surely it cannot be my responsibility to check the packet each time???? I expect a full reimbur*****t of my food that I didn't receive last night... I'm just wondering if the staff at this specific kfc is possibly doing this on purpose and taking either the money or the food? This is also the branch where my card was cloned and ***** occurred?? Frustrating and unprofessional!!
