Cidco transfer not made on my name

I bought flat in kharghar in Mar 2014 from the first owner. My society is recently registered in Jan 2020 and conveyance was made in feb 2020. The builder was reluctant to form the society and was demanding 50k from each flat owner to contribute towards a half outstanding of some deficit stamp duty to the government and other charges towards society formation and conveyance, I didn’t pay the same, since I paid all charges to the previous owner earlier at he time of purchase of my flat and I didn’t fulfilled his illegal demand of payment of 50k whereby other flat owners have paid the same in order to avoid delay in society formation. Now when the society is formed and conveyance was made and surprisingly my flat is transferred in the name of builder In the Cidco, when I’m the legal owner of the flat and have builder NOC at the time of purchase , sale agreement and other documents pertaining to my ownership and still the flat was shown in the name of builder in the Cidco transfer just because I have not paid 50k on builders demand and it was done by our society chairman who was appointed as chief promoter in this process of conveyance and who has duly submitted and signed all the documents of all flat owners who paid 50k for this process. Now my question is as to how and whom I shall held accountable for this misrepresentation and also the fact that how cidco can accept and take on record a builder who has already sold the flat and he has no power to be in the conveyance transfer list. Pls guide how should I proceed now to avoid any payment in cidco transfer now since I was the legal owner at the time of such transfer in the conveyance process and still my name didn’t recorded.
