Trai — unnecessary mental harassment bill send me after porting my no via airtel and closed services idea after one month

My mobile no [protected] has been port airtel to idea after bill payment from airtel. After porting my no into idea, airtel demanding balance bill 700.22 while i have already paid it after confirmation from airtel store and after that idea converted it. Now idea closed my services from 10 days.

So, i have paid to airtel 701/- rs dated 18/12/2017 that is no right because as per my plan was 399/-rs monthly. And airtel continues send bill send me above 500/- 700/- and 900/- while my uses under my plan. It's regarding i have already communicated to airtel after that airtel said apologize and way off and adjust bill unnecessary.

It's type mistake airtel do many time so that i have port my no from airtel to idea now airtel given me methanal harassment and demanding balance bill amount while airtel stopped my services before my porting no.

Kindly do needful for me about it.
