Lumps of mould in juice

I honestly thought this mould issue had been resolved. Purchased multiple boxes of Liqui Fruit Juice. My diabetic child was having a sugar low and so she had to drink juice rather quickly to get her sugar levels corrected, only to find some disgusting things in her glass. I cut open the box of Liqui Fruit and low and behold we found multiple clumps of mould at the bottom of the box. Needless to say, she became horribly ill. I've never been more disappointed in a product before. How is this still an issue Liqui Fruit? Expiry date is a year from now -2025. It was opened the day before my child consumed it and kept in a very cold fridge.
