Have you purchased chocolates that are part of the Mars Recall

“Mars Chocolate UK takes the precautionary step of recalling products produced in the Netherlands (Veghel) due to possibility of plastic contamination in our products”
We understand that some retailers are advising that you should return to the store from which they were purchased, whilst others are telling you to contact Mars.
Remember that your contract is with the retailer from who they were purchased. They are obliged to give you a refund or replacement. They may, however, require you to provide proof that they sold the product to you (such as a receipt). We have heard that some retailers are not requiring proof of purchase.
If the retailer asks and you do not have proof of purchase you should contact Mars
