Kindly repay my bill amount that I have made, it’s not fair to bill me on things that I never used. These are fake calls/billing which I would not like to pay.
Kindly do the needful.
I have already raised a complaint to Airtel customer support, here is the Interaction ID which I received from them
Interaction ID:[protected]

My mobile number is : 91-[protected]

Look forward to get this complaint resolved at the earliest.
