Chocolates are rotten and smelly

I have purchased 15 x Dairy Milk Cashew & Coconut chocolates 80g

The chocolates are all tasting very awful as if they are off.

The worst part of this experience is that my wife is currently pregnant and this was a very bad experience as she consumed this without realizing.

I have spent lots of money on this and the effort to go through the complaints is really not worth it!!!! Please sort this out urgently!!!!

We are very disappointed and hope to hear what Mondelez has to say about this as I plan on escalating the matter higher should I not receive a response.
