I had booked a plot of 30*40 dimensions in neo serene project by artha in april 2016. Due to sudden demise of my father in law i need to cancel the booking and get the refund amount of rs 25000. I emailed and sent reminders to artha property representative and also proptiger reps who had facilitated the booking and had assured the booking amount to be refunded in case the decision is cancelled. But now when i am calling or emailing i am not getting any response. Pls help me in getting the amount refunded. I have the booking reciepts and relevant papers for the same
