White wurms in my weetbix

In Jan/Feb i bought a 1.35 kg weet bix,In March one morning when I threw on bo**** water I saw something that look likes small white wurms,at first I thought it was just my imagination,than rhe second time I made again and i actually saw it was small white wurms,I ate that stuff and just the thought make me feel to vomit,I didnt eat weetbix again and its really been trying times as I dont work anymore and I couldt send a msgs earlier because of data. I did send an email to the email add on the box and someone did call me but I havent heard of them since. I really am disappointed in this as I loved weetbix.
