Burnt Simba Chips

I recently purchased a packet of Lays Lightly Salted chips. I was sad to find that most of the chips in the packet were burnt. Unfortunately this is not the first time I have had such an experience. I felt that I should bring it to your attention once again as it is sad to experience this so often. I would appreciate it if the necessary steps could be taken in order to rectify this as it is unfortunate for loyal customers to be disappointed every time they open a packet of chips.
