worn out food

TODAY lunch time I went fourways mall checkers to buy lunch food, got roasted veggies nad creamed spinach, I am really disappointed how could such a big brand sell ROTTEN food. I open the roasted veggies n everyone around me was welcomed with the smell, what about food poisoning ,how many customers did u sell this to ? I called the store and dey see nothing wrong all they could say is bring the food back to the store now I must drive bak to fourways mall to take back their food... I am boiling pls if u buy ua lunch there be vigilant customers...
