But in that unlimited browsing for 3months and then you have to pay ur usage wise but ia not using full of that but bill was 100% usage, but that connection was very bad slow connection it takes atleast 5minutes or 10 minutes. So i want to disconnect this internet browsing after three months i used only one month but i paid the amount 580Rs. Then i will told to disconnect
this connection they said me rest of this month you have to pay for the next month also. We told them to disconnect but they didnt you have pay 1800Rs.But we are not using connection because my system had a problem for three months we aren't using but they are asking to you have to pay otherwise it will increase whether u using or not because this is postpaid but i paid that amount to tata photon whiz.
