Worm in product

Found a worm in the strawberry rice crispy snack bar that I purchased as a snack for my son..... Luckily he only decided to eat it when I fetch him, asked me to open it for him and a found a worm nesting in the bar. I have sent an email to customer care and received no feedback. If I wasn't the one opening that bar my kid would have consumed it... In fact that bar came out of a box of 5 bars and that was the last one..... Who knows if the others did not have worms in. If I do not receive feedback today, I'm sharing the videos and images on social media platforms
