Yes bro, Dish Tv is providing BST (147fta channels) at free of cost without considering these for NCF counting. They are charging 130+ price of paid channel selected +applicable gst.
Suposse anybody selects 10 paid channels with cost of 20rs. Then he will get bst channels + 10 paid channels , which will cost 130+20+27(GST on rs.150)=₹167.
