Expired Juice for Kids in Fridge

I purchased a rascals fruit juice as well as other items for my godchild on Monday 27/04/2015 as we went for a picnic with family and friends. When we arrived at the Eco park in Green Point, I gave the juice to my 1 year old godchild to drink as she was thirsty and only to notice after she drank half of the juice that it was expired. I was very upset as Pick n Pay Express clearly does not check their goods and remove the expired things from their fridge. I contacted the call centre twice to complain about the situation but the Manager of the store has not contacted me as yet to apologise or give me a valid reason as to why there was expired juice in their fridge. Luckily my godchild did not get sick as I stopped her from drinking the juice early, if she had to finish it then she would have had a stomach bug or something.
