Numel milk not up to standard

I bought a numel medium fat dairy liquid blend milk like I usually do because I love the taste especially in my coffee however this time around I was highly disappointed.The milk only had color no taste whatsoever it was as week as weak can be .The first one I thought just maybe there was something wrong with that one then I opened another one and once again that one was just as weak as the first one.I'm so so disappointed and have wasted my money.
