Terrible quality of products

I am a frequent shopper at woolies and have been for years. Woolies service and products are deteriorating and I dont feel like customers are getting value for their money. I recently purchased a box of roasted macadamia nougat. When I opened the individual wrapped packets. It was half the size it should be. As it is these nougat are getting smaller and smaller. Is this what I pay for. I think I have been ripped of. Woolies service and products is dismissal and I feel like we our complaints go on deaf ears.
