CVS review: Milk

I bought milk on january 20, 2019. I did not have much choice. I usually buy gallon of skim milk, expiration date was january 23. I could not buy skim milk, I tried 1%, expiration was january 27. I new it will be no good. I need at least two weeks before expiration.
I am writing now because milk got spoiled yesterday january 25 and I threw it out.

This is not the first time that this happened, but it is first time I am writing about.

Ps.
I mentioned it to the manager on january 20, he was not very happy with me.
I came to the store in couple of days after, the management was very rude to me.
I have a feeling, they do not want to see me there.
