Trai — charges difference between provider

Address:

Burhanpur, Madhya Pradesh, 450331

Hi team,
I choose approx. 60 channels and airtel dth charging me 464. I think its a more than earlier.
And in my city a local provider who give approx 300 channel only 170 and 1200 for installation charges with setup box and cables.
So why these is difference between. Local provider and and big brand like tata sky and airtel digital. These is totally wrong with customers and trai always posted a notification on any channel so its a wrong.
Thank you
