Wormy and weavil oats

I bought jungle oats in the plastic type of bag, I only noticed the worms on the outside of the bag when i got home. Hoping they weren't in the bag I added milk to cook it and it was full of weavils. I called Tiger Brands sent them pics on WhatsApp as requested and still waiting for some sort of reply. This isnt the first time I've found moths or worms in their oats. So disgusting and **** service.
