Aadhaar Card — Aadhaar card delivery and related family problem

I applied for aadhaar card in september 2011 along with my wife giving my native address (Haranagar, nadia, wb). My aadhaar card was delivered to my home address in march 2012 but it was informed that my wife's card had not come. Recently family members have informed that my wife's aadhaar card has come. Due to various threats (Murder, rape etc.) from brothers and their wives, we could not go to my native place. We informed my parents regarding this but they did not do much so we stopped visiting my native place. So i informed my parents to send it to my father-in-law's place (Burdwan, wb). They informed that they sent it through registered post but even after one month it did not reach there. Finally they informed that it has returned back. As the postman is known to my father-in-law, it should not return back. This makes us doubtful whether they sent it or not. Then we informed them that we can take it from my brother who works near to my father-in-law's home but my father (Name-mich bahur rahaman) is saying that they did not accept the letter so he should not come to give it although he was agreed to come. After visiting my native home, my brother is now telling that he has forgotten to bring it although i reminded him when he was there. He is telling that he will go to home after 2 weeks and bring it. It is looking like that it may not be true fact. They are trying to force us to go there which we can't do after so many threats.in this situation, i want to inform that if this card has come recently it is ok but if it has come long time back and they were hiding for so long then what should be their's motive. Whatever the situation, we want to state that until we receive it, we should not be responsible if someone misused it. My family members will be responsible for all that.
