How to get refund amount after closure of account books of the flat?

I bought a flat in resale in IRWO project Panchkula and got it duly transferred in year 2010 and even the convince deed has been done on my name in the year 2012. At the time of transfer as per IRWO transfer policies all necessary undertakings were submitted by transferor and transferee including the affidavit signed by the transferor regarding any refund which may be there after closing of account books related to this property shall be paid to the transferee. But now IRWO has send a cheque of refund amounting Rs. 30000 at my address, but cheque is on the name of first allottee/ transferor. When I insisted them to issue the refund cheque on my name, they say it's according to rules, to be returned to the transferor. Who had actually paid the full amount to IRWO initially. So, plz clarify whether, who legally should get the refund cheque now. I have CTC copies of all such undertakings and affidavits deposited at the time of transfer at IRWO office.
