Kolkata, West Bengal

Dear sir/madam, The tracking number is EW[protected]IN. While dispatching from Belurmath the parcel contained a sandisk pendrive 8gb colour red and black. The parcel was delivered to Deoghar on 1/6/2015 but the item was not inside the parcel. I request you to look into the matter and provide me a genuine solution.
