Spoilt Milk

I purchased a 6 pk C***** 1 Lt milk from Checkers. Few days later when I came home from work the 1 cartoon burst open in my cupboard and was spilled all over with a disgusting smell. I could not take it back to Checkers as I did not have the till slip. I did email C***** and sent pictures but they hav not responded , it almost 2 months goin. Very disappointing .
