6Pack 1st Grade milk -Off and expiry date still active

I bought Parmalat Milk 1st Grade last week from Makro The expiry date is written "05/06/2021" but the Milk was smelling sour and Off .. all 6 Pack. This is the 3rd time this happens to me with parmalat Products now am Annoyed! I'm never buying parmalat products ever again and i sure as hell will discourage anyone close to me from buying it.worse this milk was for my 1year Daughter just imagine if i didn't check the Package and gave it to my Daughter ?further to my frustration due to the Lockdown i drove back to Makro and laid a complain and Parmalat office was called and was given this Ref:20-03-558 ,i have been sending emails left and right and no one seem to care to revert to me ,i need to know for the milk that cost 170 i end up paying 450 including transport cash to return the Package ,i need my petrol cash and apology for nearly ****ing my daughter with your rotten milk
