Proximagamma Pvt Ltd — took the money but not given the service or order

Address:

F-130, GF, STREET NO 7 PANDAV NAGAR NEW DELHI East Delhi DL 110091 IN, New Delhi, Delhi

I just paid rs79 through paytm for purchasing pubg mobile uc, but it shown a failure confirmation and still deducted my amount from paytm and also not given me uc also.
I just tried contacting this company also but they didn't replied my mail. I also contacted to codashop website about this but they said this it's only between me, proximagamma and pubg mobile i should contact anyone of them.
But my every try gone unsuccessful to reach that company and i felt like i lost my rs79, it's not a big amount but its mine so i need it back.
