Airtel — invalid charges added in bill without notified the customer.

Dear sir/mam,
Would like to highlight the case about airtel postpaid connection for my mbile no.[protected].
I travelled to ireland and activated internatioanl roaming pack whcih was showing rs.0 in airtel app, i activated to get otp from bank messaginh server only.

However is it the way airtel use to loot their customers by giving them a bill of rs.6000. That too without any notification.

I didn't got notified from airtel via messages or some another way. And when i am asking for justification their team even nodal officer is not replying to the mail trail. All i want is airtel will remove all wrong charged they putted in my march's 2020 bill.

I want you to please look into this matter on priority.
