Milk off

I purchased 2 x 2 litre bottle of PnP milk on Saturday 16th January at PnP Arbor crossing, Amanzimtoti.<br> I opened a bottle for coffee on Sunday morning to find the coffee tasted terrible, tried the other bottle and the same therefor had to go with out my coffee. My wife in frustration went to Woolworths and purchased their milk, all good so confirming the PnP milk was off. R40 for bad milk plus cost of frustration and travel to Woolworths and purchase of new milk. I am at a point now of not trusting PnP brands.
