Idea Cellular — Activated services without any notification, and then charged for that.

I am an Idea Customer from past 4 years. I am using others number as well of same servise provider.
In Jan'09 they have aticated the Stock updates on my number automatically and then started charging me for the same with the amount Rs 49, When the bill arrived, i came to know that for this kind of services i was charged, i was getting messages for that, and i was really annoyed by daily messages, but i thought that might be they sending to all of idea users, since i have not availed any service. Even i was not informed by any message or anything that this kind of services you have activated, so that i can request for deactivate for the same, I am seriously very annoyed with the Idea Services.

If In the recession they are lacking by some money, dont charge from our customer in this way. And even from the customer care i was getting such a cold response, "Sir you have to pay the money", Since i always the pay the bill ontime, thats why i paid the bill, but i want the rembursement for that amount.

No one is listening to me. I know it's just a matter of 100rp, but i know i earn this money.
If anyone can help me, Please help me.

Thanks
Rohit
