DishTV — i am unable choose channel of my choice on dish tv web site and mydish app

Address:

New Delhi, Delhi, 110007

My costomer id no. [protected] for dish tv at new delhi.
Dish tv is charging rs.458. And providing me the channel from its own choice and promoting their own channel by default like

Zee all in 1 hindi hd, times boquet 1 hd, marathi premium hd (Although i do not know marathi).
Dish tv web site and mydish app is not allowing to submit the chosen channel.
On submission of channel it keeps on waiting. I have tried it multiple times but it does not work. I called with my rmn to 1800108 */0* to add any particular channel but it is not working. I called to customer care no. And requested to not change my pack till 31 march 2019. But everythings failed. Dish tv is providing particular channels and blocking particular channels to access and charging rs. 458 from me.
