Kolte Patil Developers — Western avenue refund for cancelled booking

Address:	Pune, Maharashtra
Website:	westernavenue.in/campaign

I booked flat with kolte patil developers-western avenue, through their property fair abroad, as i felt i am getting a better deal (Being an nri) during the demonetisation phase.
Initially the sales person told that there will be no issue with loan but after paying booking amount of rs.50k i came to know i cannot avail loan.
I immediately met the salesperson and collected all my post dated cheques informing him to initiate my refund. First he told as he is travelling india next week he will direct refund the amount in my account. But it didn't happen.
2 weeks later he told as he was busy with another propery fair so he will initiate the process, another 1 month from that date (6 weeks) and i am still struggling to get my money back. Everytime the sales person says it will take 10 days and i have to chase them. Didn't expect this unprofessional behaviour with reputed developer.
