Trai — independent dth fraud

Address:

In front of radio station Jajolai, Nagaur, Rajasthan, 341001

Hello sir, i purchased independent dth on 5th of december 2018. I paid 2000 for 1 year subscription. But now independent dth is not showing all channels which they promised. And from some days all channels are freezing continuously after every 10 seconds. I can’t even watch a single channel and some days ago none of star channels were available on independent dth. They promised 21 hd channels but now not even a single hd channel is available. I feel like cheated and i want my refund from independent dth.
Thanks
