Airtel — Airtel Fraud - ISD CHARGED Even when No ISD call was done

Complaint about: airtel mobile bill (349 rs family plan)
Airtel has charged isd calls in my mobile bill. No isd calls were made from my numbers but they had very well presented the charges with fraudulent call details. They have given details of the isd calls in itemized bill, but those all are fake as no such calls were made from my numbers. I have been extra charged for 1 isd call (336 rs). I never do any isd calls from my number.

I called there customer care today 8 july and the representative assured Billing on your Airtel Number ****835348. Service Request No.[protected], dated 08/07/2022. Rest assured, we will work on the same and get back to you with an update by 11/7/2022.

But this is a very bad experience being a AIRTEL CUSTOMER FROM 15 years
