to who so ever it may concern,
i abhishek ghosh, an employee of DLF Pramerica Insurance co Ltd, was scheduled to travel to Bangkok today, on 2nd of April, my passport was issued by the passport office, on 28th of mar and the same left for my address on 29th via speed post. the concerned authority from the howrah gpo, had disposed that particular passport in a particular bag number for my destination address, the concerned authority in hooghly (telenipara) po, claims that they never received that particular parcel bag that left for hooghly on 30th of march. whereas similar bags of posts dated 2nd of april were received by the post office concerned. as there is no traces of my paasport and i missed my bangkok trip which was a official trip and matterd to me a lot. where a training was organised on my company behalf, due to the negligence and irresponsible behavior of the post authority i had failed my trip and suffered a huge loss.
i therefore request for the necessary actions for the same, and demand for such a irresponsible behavior of such an important document and my mental and monetary loss.
