Damaged in 60 minutes

Its the third time now. These people send me damaged goods. How is it someone can put a bottle head next to a paperbag, and not expect that the bottle head will puncture the sugar bag. Spinach in containers come open with all the spinach squashed by the other items. Today my avos were placed under a heavy box containing catfood, resulting in the avos being mushed and squashed. I get the feeling that these packers and drivers purposely damage goods or pack incorrectly so that customers are inconvenienced. Y should we trip the driver when in every occasion the goods come damaged or completely destroyed. I dont even think these people care either way. Y arent they supervised .
