Sour C***** Milk

I have used c***** milk for as long as my life and always have been doubtful about other brands .I have a coffee shop since 2016 and have also only settled for c***** milk since ..Of late rhe milk is not up to standard and has bèen brought to attention of C***** consumer division.This is almost a month ago .However after discussions with family and friends ,we all seem to be sharing the same experiences with the milk goin sour way before expiriy dates even if the milk was kept under recommended temps The rep from c***** did confirm a problem on production line telephonically with me .How many of us are still experiencing similar issues with C***** milk.?
