I am a seafarer and had applied for Indian seaman book (Cdc) in February 2019. The address at the time was in Tamil Nadu. It took around 3 months to get that cdc delivered but I relocated to Dubai where is my work place, so it got returned undelivered to dg shipping Kolkata.
I tried several times to reclaim it through the e mail and I got one time reply that I need to send 50 Rs stamp along with one reference letter I did the same twice the time in two months gap and then I have acknowledged them through e mail many times but no response at all. Please through this complaint is there any possibility to get my Indian CDC or not.. Because I am tired of this please help me out..
