Bad customer service

I had a horrible experience this morning with the manager at ABC sweets (Centurion Crescent) Yesterday I purchased zoom juices in a pack of 12. This morning as I was packing the juices I realised that most of the juices were leaking from the top and had damaged the party packs I had packed for my doughters birthday. I went to the store in the morning to ask for a refund as I cannot purchase an item I am not happy with. I went there with my proof of purchase and I found the manager. I tired explaining to him the damage if the juices and he kept on cutting me off being extremely rude to me and telling me even if I expose him he doesn't care and he will not replace or refund me and he doesn't care because it's not his fault.
