R22 for a bag of air

<p>I just purchased a bag of Roasted Hummus Garlic crackers only to discover there was a total of 5 tiny crackers in the bag! The net weight is 50g however when i weighed it it was 10g! This is such absurdity, my last complaint related to apples that had a chemical taste, is there no quality control at Woolworths???</p>
