So I just wasted 5 mins and noted down price of all Bengali channels (SD) under this new rule to see what the total Bengali package price comes to and after adding them it comes to a total of Rs. 61 PM. As far as I see there's NINE (9) pay channels and the rest are free. Now if you directly compare the Bengali package price only under this new rule compared to old one, then it's reduced by 6 rupees, yes. Because currently the Bengali package costs 67 rupees PM.
But there is that 130 PM mandatory rule, regardless whatever 1 or 75 channel you choose. So taking into account that price would be, under the new rule, for simply the Bengali package would be:
130 + 61 + 18% GST = Rs. 225 Per Month
Under old rule you needed to pay Rs. 166 Per Month for the same (My Pack 99 + Bengali Pack 67).
Nutshell: A 35% increase under new rule.
Ok.
