Supertech Limited — advance payment refund issue - super tech hilltown sohna road

Address:	Gautam Buddh Nagar, Uttar Pradesh, 201307
Website:	www.supertechlimited.com

I had made a booking for a 2 bhk flat in supertech hilltown sohna road, south gurgaon.
The sales guy mr harish convinced me to pay a booking amount of rs 50000 on 22nd july 2018, proof of which is attached.
I told him that i am not sure about my eligibility of the loan amount which was needed. But he said if the loan amount is not granted, the paid amount will be refunded.
Unfortunately the loan amount was not granted due to my existing obligations. Since then i have been trying to contact him, but he is not responding to my calls, emails or messages. I even tried to contact supertech customer care, they are also not responding. I visited supertech office at noida, they said i need to contact the sales person for this.

I don't know how to proceed with it. Its a huge sum of money and i don't want to lose it.

Attached is the proof of payment made against supertech limited.
