Bharti-Airtel
Fraudulantly charging for unprovided service

My no. is 9979853315 (post-paid) of airtel.

Today on 22/02 at 12:28 pm I have received a massage as follows from no. 54321:

Thanks for downloading PubGames from Airtel. You have been charged Rs 99. Filmy Buzz and Pics *321*69#

But actually I have not downloaded or click any link for this kind of stuff. In past also I have been charged same like this for two times. On inquire of this on customercare (121) I got answer that they can't do anything because they are not able to find that what was actually going on.

So plese take some rapid & legal steps on this matter.
