Bharat Sanchar Nigam [BSNL] — stupid bsnl

Bsnl services are the worst, once, only once i ran more internet than i was allowed to in a month and i was supposed to get a warning. As soon as i open any document or file or website or anything that uses even a hint of internet it used appear, unable to find following command: http://173//bsnl/132/promotionalmessage.
And it was in html, luck for me i knew html i ran across every document extracting then.. Finding a way to open up things and finally
I ended up finding nothing, how do you ask? There was this weird signal hitting my computer and destroying every html document.
Now even my kids game says incorrect details by updator, and this wont stop, i dont know until when.
