[Resolved]  Idea Net Setter — 75% hike in tariff

I had purchased from jodhpur an Idea net setter( [protected]) in march 26th 2009 for RS 2500 flat which had unlimited net usage and download for monthly recharge for Rs 400 per month.Just after two month they have stopped the recharge of Rs 400 and hiked the recharge price to Rs 699 per month.An increase of about 75% in just two month.This is clearly a case of cheating customers.I want to complaint about this irregular and unjustified behaviour of hiking.I had to recharge with Rs 699 otherwise My business would have suffered.
I want my extra 300Rs back which they had charged me extra and also make the celluler companies to stop these practice
