Bad service by selling food about to expire in few hours

Bought kfc feast 6 pieces on 23/09/18 . Was given 3mini loaves that expire on the 24th ( within 7 hrs of purchase). I went to the outlet I bought from, supervisor Shorley was called as I wanted an exchange she told me that it's impossible to exchange as the policy states that they can issue the loaves and should we get food poisoning they will cover the medical costs incurred. She told me to bring the meal I bought but I had already ate the chicken. Also she told me that the loaves were free I guess it means I should not complain. She told all the mini loaves were expiring on the 24th and there's no way I can get an exchange forcing that it's either I get a refund of R10 or there's nothing she can do. I took the mini loaves home despite the expiring date. I guess kfc promotes consumption of stale food. Am I forced to consume all the meals I buy at kfc within 7hrs of purchase?
