Supertech Limited — Refund against cancellation

Address: Gautam Buddh Nagar, Uttar Pradesh, 201001

Website: www.supertechlimited.comn

I had made booking for a 2bhk flat in Supertech Hues project in Gurgaon with 5 lacs as booking amount in the month of April 2015. I approached the builder to cancel the booking in very next month as the flat is not as per my expectations. I asked the builder to refund the amount against the cancellation. But since then the journey of my problem had started. I have made several phone calls and visit the builder office, but not received any solution. I have not signed any builder buyer agreement it is just a provisional booking form which I have signed. Builder is not agree to refund the amount.
Iam salaried person, this 5 lac is my hard earned money which I have saved by deducting my other needs. I pay tax regularly. How can the builder take my whole money, these builders are very rich, use luxury cars, live in luxury home, but when asked to refund than they are not ready to return a single penny.
