Mondelez India Foods / Cadbury India — cadbury dairy milk silk roast almond

Hello. I wanted to know whether cadbury dairy milk silk is haram or not? It has green sign on it which means its vegan. But some reliable sources confirmed that these chocolates r not halal. What do u mean by not halal. Do u mean haram or just that it is not certified halal. If not hala then why it is not halal? Do u use pig fat or pig dna in these chocolates. Also, why dont you exactly clarify which one o[censored]r chocolates are haram and not suitable for muslims? Can a muslim eat cadbury dairy milk silk roast almond and whole hazelnut flavor.
Please let me know.
Thanking you,
Ayesha akter.
