Airtel — wrong bill amount for [protected]

My number is [protected] i have subscribed for 2499 plan and a child number is free in this plan. When i received my bill, there is a rental charged for child number too.

As discussed earlier with nodal officer, he clearly told me that "you will not charge a single rupee for child number".

I have send mail regarding this so many times but there is no resolution.

There was one more issue that i cant manage my child number in my airtel app.

Every time c. Care team said that it will resolver in 24 hrs. But problem is still pending.
