How to get refund from the builder due to cancellation of a Flat booking in Bangalore?



We had booked a flat with one of the leading building developers and construction groups in Bangalore. Due to some reasons, we had to cancel the booking of our flat with the developer. But we had already paid the required 20% down-payment for the flat booking.

Now, the struggle of getting the refund from the builder has been going on since May 2017. But the developer/construction group is reluctant in giving back our money and has been making excuses for delaying the refund amount.

Please advise what steps can be taken to get the refund from the builder.
