Society noc

I am staying in my flat since last 47 years. I have purchased my flat say 'A' from my relative 'X' who is founder member of society for which I have share certificate issued from society. However, while possession the original founder member has exchanged his flat with other founder member's (Y) flat say 'B'. X has another share certificate for flat B showing transfer from X to Y. Both share certificates have same date. Now society is refusing both of us i.e. I and X for issuing NOC when we are applying to regularise our transfers in collector office (as it is a collector land). I am staying in X's flat for last 47 years paying all dues of society, infact I was a committee member for more than 20 years. Similarly, X is staying in flat B since last 47 years. In 2008 ABHAY YOJNA, we received our respective flat stamp duty notices and paid stamp duties too. We have written 3 letters to society for issuing NOC but they are adamant and written to collector against it. Now society has also moved to registrar for cancellation of my membership. Your opinions are requested.
