Bad #Pronutro

This is the third box of #Pronutro that has a bad smell and even worse taste that is inedible. The first time I ignored it and just through it away. The second time I emailed #Pioneerfoods I had no successful outcome. Now is the third time and I don't know what to do. In the past years there was never a problem with #Pronutro. But since a year back the smell and taste is awful 😖
