Godrej Properties — Refund of Booking Amount on Cancellation

Address: Thane West

I had booked flat Godrej Ascend at Thane Kolshet Road. Upon booking, they got one big form signed and filled. After 6 days of booking due to financial situation at my end, I put cancellation request within 6 daysof booking.
Now Sales Manager at Ascend is saying 5Lacs rs are forefited. whereas as per RERA guidelines builder is supposed to pay back full booking amount if cancellation request is put within 15 days.

Feel cheated by Godrej Properties. It just has big name but at ground level Sales team is really really bad at service and not replying to calls properly now and not replying to emails as well.
