Airtel — unnecessarily deduction of money

Excuse me, you airtel...
My 20 rs. Got deducted from my account unnecessarily, and i am getting a very stupid reason for this that i have used some kind of prime zone services, but the actual fact stands that i have not.
So, it would be better for you to contact me as soon as possible otherwise you are likely gonna face consequences. I will be taking a very strict action against you or will move to consumer court because i am not the only person who is facing such kind of problems and i am not likely to keep quiet as everyone else so better deal with it.
I will take a strict action so its better to reply to my complaint otherwise i will be taking action... And you better mind it...
