Fair Cape Long Life Milk Bad Smell

Hi, I bought 3 x 6lt fair cape full cream eco fresh long life milk from Pick 'n Pay online shopping. The milk has a strange smell. It isn't sour but there is something wrong with it. It tastes funny aswell.

Can you please advise how do I get a replacement? What is going on? I have bought fair cape milk multiple times.
