Can society change parking alloted by builder to other person

We had purchased the stilt parking from builder on 6/8/2009 & builder provide us parking allotment letter. afterwords we haven't look to parking space since property is on rent & various tenant residing in property till 2018 doesn't had car so we never look into our parking. The Last tenant residing in property had car so he coordinate with society & gets parking permission. one day when we checked tenant parking location, we found that the current location of parking allotted to tenant is at different location than builder parking allotment location to us but parking number is same. To clarify this, one day my dad visited society office and he found that around year 2012-2015 during AGM meeting there was decision made to reallocate unused/empty parking space & due to some reason my dad not able to attend AGM meeting during that year. I asked the dad whether society has taken our consent to change our parking, he told me that society had not taken permission nor contact on this topic. This year, i ask society to provide us our original parking. Now they are saying this so many year, you are sleeping & giving example of past AGM meeting whether parking re-allotment is done. When ask about original builder document where it should me mention, they are saying that they don't have any document from builder. Now i am stuck with since new parking location is far away from lift & having leakage problem. My question that 1. whether society can change parking space allotted to by builder without owner permission ? 2. Can i file case with registrar of society to get our original parking space back ?
