Worms in chocolate- Beacon Heavenly selection

I found worms in my chocolate, stale tinkies and a freaking packet of chipniks with some weird black unknown substance in it ,I dont have R100 to throw around, that was meant to be my dads fathers day gift,I have been trying to get hold of Tiger Brands with absolutely no success, you'll are a disgrace to do this to people especially during COVID 19 when money is already scarce
