Very Unhappy Customer

I bought a box of the Lindt Nuxor with milk chocolate at Checkers and when I opened the box the chocolates appeared to have this white like colour almost like it was laid in powder. I do not know what it is or if it's harmful but I would rather not take my chances I'm just very disappointed with the quality of the chocolates this cannot be acceptable I brought it to Lindt Chocolate's attention and they more concerned about proof of purchase When I bought the chocolates I didn't eat it immediately and when I eventually decided to eat it I noticed it was not okay to eat. Instead of doing something regarding their faulty products they more concerned about a slip. No one even bothered calling me to explain what was wrong with the chocolate or why it looked the way it did I guess their customer service is just as bad as the products they sell. I personally would never buy another Lindt product again
