I changed my bsnl broadband plan from Home-250 to 750 ul on 20 december 2009.And I received bill of around 1350 (I have dataone phone line with outgoing disabled, fixed charge 120 /month )This time I tried to revert back to h-250 plan from 1st of July but my post paid order shows that my plan changed(from750-ul to 250) from 3rd July 2010.So how much bill should I expect for this month of July 2010.I,m afraid it will be something like (750+250+60+120) + 12%
