Unhappy customer

Hi,I am a customer at pic n pay,I buy my groceries every month,this month when I did my grocery,I bought a pack of 24 cappy juice ,and when I got home it was an apple flavour and when I opened and drank It tasted like an expired fruits or it stayed for a long time in the store r8,I don't know. I buy cappy every month but this one it was a no no,I tried to open others to check if I am certain and it was the same.i am not happy at all.and cappy is not cheap to loose money like that. And I bought it for school when it opens but pic n pay disappointed me this time
