We recently purchased 6 boxes of TACOBELL taco shells made by Kraft Foods. Every single box of shells is rancid, they smell horrible and we've had to throw all of them out. I searched the entire Kraft Foods website looking for a place to enter a complaint and none such exists. I've never encountered a website by a major company that didn't have a complaint center and offered some resolution to your complaint and discontent. Kraft offers none of that on their website. I will never buy TacoBell products from Kraft again, the smell of the taco shells was enough to take away your appetite!
