Unhappy customer

I am very dispointed i bought milk at your store open a box in last week thats in the fridge and i see the cream told my its probaly just over creamy. ....when i drank it the mile was off i needed to trow a whole half box away....then 2nite i made again a cup of and the milk is sour again the expired is feb 2024.. I mean a person pays alot for WW products because i believe its qaulity but if this is happening to your milk once open i dont know of your qaulity
