BAD QUALITY MILK: CRYSTAL VALLEY

I would like to know why Shoprite stocks and sells the lowest quality dairy products. Crystal Valley is the worst. Their UVF milk in cartons are off within expiry dates and tastes like soap. Poured into a glass, it forms a large, sopay dome on top. Do you ever check the quality of these products before selling them to the public? Extremely ********* and dangerous to continue selling duds to the public. Yes, I had to throw it away. Money wasted.
