Idea Cellular Ltd. — Idea - Unnecessarily Deduction of my Balance

Address:

Pune, Maharashtra

My mobile no. is [protected].
I got a message today (24/12/2012) from IZideaCMS saying that thanks for downloading the song and charges for this are Rs.15.and my balance got deducted by Rs.15.
Without any option selected i got this message. I called up to customer care 198 and complaint about this but she (Swati) was not agreeing and saying, using internet, I have downloaded this song. I told her, my mobile does not have internet facility, and I haven't used internet from the phone, ever since I have taken this connection last year. But, she was not agreeing and asked me to call 12345 and inform them.
When I called 12345, the person again told the same thing, and they cannot refund this amount. I told him to check, how the amount got deducted, when I have not used. But he doesn't even listen and told me to call again after 4hrs, when his senior will come.

3-4 months back also, 3 times, my money got deducted in the same way. At that time also, nothing was solved.
Now i am worried whether they will give my money back or not as this has become each and every company’s policy to deduct customer's money without any reason. So please help me.
