I found Worms and webs in my Morvite very angry

Good day,<br> <br> I purchased a few bags of morvite for my kids to eat as they love it only to find worms and webs this is not the first time I have found this (it might be harmless) but it makes me question the hygiene aspect of things I am very angry about this and expect a reasonable explanation or i will take this further. I am tired of wating my money on your products.<br> <br> Regards<br> Jolene
