Airtel — incorrect charges [protected]

Hi,

In my airtel bill for the period: 05-jul-2017 to 04-aug-2017 bill no:[protected], reflecting as international sms to the number:[protected], 5 times. Details is as:

05/jul/2017 02:20:[protected]
05/jul/2017 14:44:[protected]
06/jul/2017 07:15:[protected]

But i haven't send any sms to that number and i have no idea about that number. When i checked online the same number found for fraud in other service provider too. I guess its a fraud from the company. You have charged 25 rs for 5 messages, 5rs per sms. I want this to be solved.
