Godrej Properties — godrej nirvaan, token money not being returned

This is regarding the recently launched godrej property "godrej nirvaan". My parents went to enquire about this property on 29th september and paid the token money of rs 27000 to be a part of the launch event on 30th september. They had clearly stated the requirement of east facing house and same was promised. On 30th september mr saha promised an east facing flat and showed the floor plan of 01 series flat but after booking allotted 1005 (05 series, west facing).
After realizing this we asked him about this and then he started giving excuses that there was a miscommunication. Now when he agreed that he has made a mistake we said that we do not want the flat since its not east facing and for safety blocked the booking amount cheque of roughly rs 3, 11, 000. But they are not returning the token amount of rs 27000. Please help in getting the money back
