Vodafone Idea Ltd — Handset Inbuilt Game Pack Activated Without Request 2

My Brother got a SMS on his mobile number [protected] as below.

Hello!
Thank you for choosing to access Handset Inbuilt Games, You have been charged Rs. 25

But he has never requested for this pack and never touched any link of saying of the same.

Kindly deactivate the pack and reverse the charge from the bill
