Airtel — non used international data roaming charges applied while in transit

Hi airtel team,

I have been applied with non used international data roaming charges on my postapid number and bill amount is approx. 20000+, which is just not feasible for me to pay the huge amount.
Though i have been provided with a 4720 waiver off on these, from nodal office, but it was agreed, that i would be only able to pay the bill amount of 50% out of these charges.
Kindly provide me waiver off, of further 5000rs. So that i can pay the amount remaining.
Further, as i have been paying my monthly rental regularly, so it comes from no where, that you can barr my number services.
Kindly un-barred all the services on my postpaid number, as i am facing all sort of banking and financial issues, due to the number not in active state.

For any further discussion, please call me at my alternate number - [protected].

Request you to immediately unbarr all the services on my postpaid number.
