Is it Chai Seed or is it Poppy...

I recently bought a 1kg packet of Chai seeds from Cab foods in Brackenfell. After consuming nearly half of the bag I kept feeling a cruchiness while consuming my chai seeds which is soaked in warm water hours before drinking it. I thought it was my imagination and then my partner experienced the same thing. After inspecting the bag more closely and to our astonishment it was mixed with poppy seeds. I then found out that friend of mine had the same thing with her chai seeds a few months ago. I have contacted CAB foods but to date have not had any feedback from them on this. I find this to be exceptionally worrying as we are paying for Chai Seeds not a mixture of Chai and Poppy seeds. I have to ask myself this question, Are they trying to cut costs by making us think we are buying pure Chai Seeds!!!! I find their customer service to be very poor almost non responsive. I queried this 3 days ago and to date still no feedback...
