One97 Communications — balance deduction from my idea network number

My number [protected].
I am an idea customer and repeatedly money is being deducted from my account. I have not downloaded anything from internet but still i m getting message from idea mentioning that...
Dear customer,
Thank you for downloading contestpack from one97. You have been deducted rs.w

This is not the first time it's happening.

Kindly stop the deduction immediately and resolve the issue at the earliest.

Thanks & regards
