Mondelez India Foods / Cadbury India — dairy milk silk oreo -, taste like wax or oil

Dear cadbury,
i am akhil from kerala. Me and my family loved every chocolates from cadbury. But just now i baught a diary milk silk oreo from a retailer, seals where not opened. I opened it and shared it with my family. Every one spit it out. Then i tried, it was horrible. It taste like wax or something. So please ensure the quality of the product. I was planning to give the thing to the food and safety department. But not doing it now. So please ensure u are taking action to maintain the quality. Each and every penny  has value. Please give a quality product for the customers. I felt so bad thats the reason i am writing the mail this late night.
