Exploreindia - Refund not processed by exploreindia co in Sonipat Haryana

I wanted to go on a small trip at Alibaug and Lonavala for * days. So I entered my requirements on all famous travel & tour sites like MMT, YATRA, etc.
Then I got a call from Kavya Sharma who is in the sales department of Exploreindia (Sonipat, Haryana) on **th December ****. And she offered me the same package in **K and mailed me the itinerary details.
The package price offered to me was very less(In my budget) compare to other travel packages. Before making the payment, I visited their website(www.exploreindia.co.in) which was looking OK to me and also I had a call with Miss Kavya Sharma regarding payment. And She was like "sir aap mujhpe trust kerke payment ker dijiye hum fraud nhi hai".
Then I made the payment of Rs.**** on **th December using GPay & she promised me to get the booking details in next day on **th. On **th I started asking for my booking details then she replied that she has informed in booking team & they will get back to me.
I also had call with their head Chandrabhan Sharma (from Booking team) on **th Dec who also known as Arun. His word was like “**** leke mai apna business itna bada nhi ker lunga isiliye trust kijiye hum apko service denge” and they will provide me all the booking details by **th Dec.
On **th Dec, I got the confirmation mail from Chandrabhan Sharma (from Booking team) of Advance Payment Rs. ****/- done by me with a receipt which does not have the GST No. on it.
I waited till **th Dec and I started mailing & calling them regarding my booking details but they did not respond properly. Now Kavya Sharma from sales team stopped answering my messages on whatsapp & call.
On **st I called Chandrabhan Sharma for getting my booking details and he was like sir you have to pay rest Rs. **** and then I will get the booking details. And this was not communicated earlier neither by Kavya nor by Chandrabhan.

I called the hotels which Kavya mentioned on itinerary and both the hotels denied any booking on my name or on exploreindia for that particular date (**th ,**th & **th Dec).

Hence I decided to cancel my trip with exploreindia and I dropped a cancellation mail to booking team on **st of Dec and I communicated same on call to Chandrbhan & asked him to revert on mail to initiate the refund process.

And they had mentioned their cancellation and Refund policy on itinerary and according to that I had cancel my trip before * days of departure & I should get full refund as mentioned by them. In one of call Chandrbhan told me to clear the refund process in * days but till now I did not get any mail of refund or refund in my account.
