All Bran Flakes

I recently purchased (24th May 2015 @ 16:43pm) a 1KG box of ALL BRAN FLAKES from Pick N Pay Clearwater.<br> <br> I opened the box today and when I added milk tasted like the cereal was burnt. We even had nausea when trying to consume the product. <br> <br> The best before date is 05/03/2016, the numbers in between are 05:20:38 L6. The production date is 05/03/2015. I even have the proof of where I purchased the product.<br> <br> I will not consume the product. I do enjoy the product however with this experience I will no longer consume any product of the Kellogg's brand and I would like to be reimbursed for the Kellogg's products I have purchased. I am no longer confident in your product<br> <br> Kellogg's has the guarantee for what purposes?
