Den Networks — regarding complaint of den cable, operator in unnao-209861 u. p. east

Address:

Unnao, Uttar Pradesh, 209861

The cable operator executive of den network in my area (Shuklaganj, unnao, uttar pradesh, pin - 209861) is taking extra charges if i am choosing a plan built on my own.
The executive is saying that i have to pay extra rs.20 for every slab of 25 channels.

Though on trai channel selector i built that pack including ftas and 5 broadcaster bouquets namely-

1. Star hindi value pack - rs.49
2. Zee family hindi pack sd - rs. 39
3. Tv 18 budget pack - rs.22
4. Sony happy india 31- rs.31
5. Disney universal bouquet - rs. 10

And by including nfc charges + gst @ 18%, total monthly cost at trai website was calculated to be rs.331.58.

But the cable operator was arguing that there is additional charge of rs. 20 for every slab of 25 channels and according to him my pack would cost me rs.403. But, trai website showed rs. 331.58 inclusive of all charges and taxes.

Kindly register my complain and provide me with the information if there is actually a charge of rs.20 for a slab of 25 channels according to the plan i have chosen.
And, why den operator is asking for more amount.

Thank you!
