Awful Tasting Powder Milk

I use to buy crystal valley powder milk in the past, then it was on par with other brands. It has been three months now since I stopped buying it because of an awful after taste it developed. Today I bought two packages from Shoprite, hoping that awful batch will be finished by now. What a disappointment! that awful taste is still there. Crystal Valley standard has terribly dropped. YOU HAVE LOST A VERY LOYAL CUSTOMER. I am done with your products!
