Aaaah... good for you for staying strong! It's easy for them to say that they didn't change the ingredients because there's no proof, but I'm glad that you're confident in the fact that you know what you saw and that others saw it as well. They know the truth, and when you reply in such a confident manner, THEY know that you know the truth. Maybe you could get other witnesses to mail as well? At any rate, don't let them get you down, you're doing great!
