Cadbury Dairy Milk — Dairy milk chocolate Rotten

Dear sir/mam,
I purchased to silk chocolate yesterday. While opening the first chocolate I could smell rotten oil from the package. I ignored it and opened the package to see intact chocolate bar with white layer above it. I tasted the chocolate since in package it was recommend that whitish layer won't affect the fitness for consumption but it was good and tased very bad and the chocolate felt like sand on my tongue. So i threw away the bar and tried opening the second one and the result was same. I strongly recommend to maintain good products and recommend refund for the faulty ones that I have purchased.
I have included the bar code of the second chocolate for your reference so you could withdraw the faulty batch from the public sales.

With regards
Swathi.
