MTNL Data Card 3G Jadoo — MTNL data card not working

Address:

Delhi

I have purchased a MTNL data card 3 g jadoo in april2011 and recharge iton 25th april 2011, with Rs.4500.00 for six months unlimited data download and unlimited use as claimed by MTNL. It works very well for a month after one months it stops working, and when I call 1500 MTNL customer care , they gave me contradictory answers, One person saying your amount is finished due to some service activated itself, He didnot know that service, another person tell me that it is nothing to do with the your balance amount as my plan is already activated for six month against the above said amount. But they donot provide me any solution. Please look into the matter,
As I have no internet service since last month. Please Make it clear whether MTNL either give me proper service or return my money, which they deducted and cheat me .
