2lt full cream milk c*****

Hi my name is pulane ihv complains abt the 2lt milk it looks like it's mixed with water inside I've returned it to the store couple of times but lastwik the milk wen use it it was already spoiled so dnt know if the quality has been compromised or what but I really am not happy at all with the 2lt milk full cream c***** I bought at ratanda shoprite but even when I went at heidelberg experienced the same so I'm assuming it's a c***** that has problem not the store
