Unisyn Enterprises — amount paid for tata sky installation - no response till date - refund request

One of executives from unisyn enterprises company came to my home on 10/8/2019 by name madhavarao and johnvictor (Mobile: [protected]). He has asked to pay the money through paytm to install the tata sky connection. I've paid the money to unisyn enterprises on the same day through paytm. Till now i did not receive any call from tatasky. The executive is not attending my calls and not giving me the current status. I am confused here.

I request unisyn enterprises to refund my money.
