Airtel — balance cut over a period of time and account deactivated!

About 6 months ago, i accidentally recharged my airtel sim with 200 rs top up instead o[censored]nlimited plan. Afterwards i haven't used that sim since i couldn't convert my balance into any prepaid plans. Over a period of time, without usage, my sim balance got reduced to 70rs. As shown in the attachment, i suppose they have deducted 23rs from my account balance for many times. Then i activated data plan for one month in that sim in order to give some usage to the sim. Then my balance got reduced to 21rs, and after 19 april 2019, my sim got deactivated. Since the trai has asked mobile service providers not to deactivate a sim till the subscriber has the minimum balance amount, they're simply deducting money to make the balance less than the minimum amount in order to deactivate the account. Kindly find a solution to this issue as trai has already instructed telecom companies not to deactivate the account if it has the minimum account balance.
