Xrbia Vangani — fraud while refunding xrbia vangani

I bought a house in xrbia vangani, f3-202 around 12.5 lakhs approx.in the month of june 2017. Due to some heavy gst, our monthly emi went up and we decided not to go forward in the month of oct/nov 2017. We paid around 1, 96, 000.
I told them and had a meeting as well with them that we won't be going ahead and filled every form that was possible and even i emailed them that please refund our money back after deducting appropriate amount like 10% of our flat price which will be around 1, 20, 000 approx. On 17-june-18 they called us and said that you won't be getting any refund and all those people which you spoke with are juniors that won't be counted and the guy which we spoke with called nilesh in chembur branch said that he is the senior person and he takes the final call. We told him that this is absolutely wrong and you are not suppose to take money from us like that even if all the people which we spoke with said that you will get the refund. Now, i am like totally devastated because of this kind of fraud they did to us.
