Flavor Has Changed

I have been purchasing these for years, especially when on sale, I buy quite a few to have them in the freezer for a quick meal. They were always delicious, great cheesy sauce. I purchased 6 packages not that long ago, and just took 2 out the other night and both my husband and myself thought they tasted awful. To me it tasted like the mac and cheese had lots of corn starch as thickener in it and not a good cheese sauce at all. My husband said it was lousy and not cheesy like the sauce use to be.
My sister buys them too and texting with her about them, she said she doesn't like them anymore either. They are totally different then the original.
Sadly we would presume to save money, they changed the recipe; they have lost our business and my sister's and we will not be buying them again.
