Indepandant Tv - Fraud done by the company

I was looking for a new DTH connection and I choose Independent tv for this. I talked several times at its toll-free number, left requests for contact back at its website also regarding new connection but not a single attempt was done by independent tv to contact a customer for his grievances. Every time when I used to call I was told that whenever new connections will start independent tv will contact me. But it was not done for a single time.
Finally, on *nd April ****, I saw at its website that the new DTH connections have been started. So, I booked a DTH connection and paid Rs. ****.** instantly through Paytm having order ID No.*****. But now I am feeling that I have made a wrong decision to choose independent tv for a new DTH connection because after passing six days period not a single response is received from its side regarding confirmation of my request, payment and installation schedule. I am continuously mailing to independent tv but it has turned a deaf ear towards customer grievances. It is worthwhile to mention here that the toll-free number posted on its website ( i.e. ***********) is also making fake commitments and giving wrong information. It is very ashamed that where other counterpart DTH provider companies are very careful about their customer and providing their services quickly and installing connections within two hours of application, I have been waiting for * days because I did a mistake to choose Independent tv.
Please suggest me how can I get my above payment back. I hope you will reply to me.
