Sour Milk

So on the 25th of November 2020, we bought Pick n Pay Long Life "fresh" milk , two 6 pack boxes. We opened the 1st box, milk a bitter taste . Tried a second box, this was even worse. Upon returning the milk to Pick n Pay Diepkloof Square , we were handed the R150 like I am the one who's inconveniencing them. No apology, not a care in the world. Truly disgusted by the attitude
