Imposing FUP is the only way to slap such exploiters.
I use 250 GB per month in my BSNL fiber Rs.779 plan (100 Mbps till 1000 GB and 5 Mbps after 1000 GB) all devices combined + 30 GB 4G data per month in my main number that has 2 GB data per day plan + 5 GB approx per monthb5G data combined usage of my main and secondary number. I am not a exploiter. Now a days I don't like films because those are not all worth to even download from the pirated websites. I only watch news only upton1 hour per month. Thats all.
