Simba Niknaks running a ****

This is about Simba Cheese Niknaks. I buy Simba Niknaks in the bag of 50 times 20gram packets, regulary. On a few occations I have found 2 to three packets out of the 50 that did not weight 20g. And now I have found 2 packets that is empty. With all these findings I have emailed simba talkto to show them evidents and to explain my concerns. I only received acknowledgements of the emails received but nothing in terms of what is to be done to remedy the situation. So if I get three of these flat packs it means for every bag of 50 pkts they only gave me 49 pkts or even less. They are conning poor people out of our hard earned cash. Imagine loosing 4% per bag!. 3 bags per month = R105 my cost = R4.20 per month = R50.40 per annum...THATS JUST ME. Disgusting.
