MOLDY ROTTEN OBJECT FOUND IN KELLOGS COCO POPS

On the 8th Feb 2018 i poured out coco pops into bowls for my sons and to my absolute disgust a rotten moldy stone looking object rolled out, i immediately took pictures and reported it to Kelloggs as my sons have already eaten cereal from that box for two days prior. I insisted that the object get tested and that i was provided feedback asap. Clearly Kelloggs has no interest in their clients nor takes any accountability for this issue. the item was collected on the 13th Feb, i then received the one and only phone call from consumer affairs on the 20th Feb who then asked me if the item was collected, later that day DHL had arrived to collect the item, it so happens that the driver had remembered that he had collected this from me a week earlier. Since then i did not received any communication from Kelloggs. I would appreciate some sort of feedback regarding this matter, my sons had fallen mildly ill but there is not telling if it was because of what was in that box thanks to your lack of urgency, on the other hand maybe it was your strategy all along!
