Airtel — airtel mobile number [protected] automatically activate international roaming and amount deducted from my main mobile balance

Address:

New Delhi, Delhi

I am using airtel mobile number given in the subject, of delhi. Being a defence person, presently i am serving at pithoragarh, uttarakhand. My mobile was on national roaming.
On 11 sep 2017, my above mobile number automatically stopped; no network shows. And on restoring network, an sms received from airtel that international roaming charges is rs 99. Due to low balance now rs 9.51 has been deducted and balance rs 89.49 will be deducted subsequently.
Prior to activation of international roaming, approx rs 60 to 70 was my mobile balance. But before i receive the above sms, i was received incoming calls. Therefore my balance deducted due to international roaming.

I mean to say i was very much in pithoragarh in india. International roaming activation on my mobile was due to technical problems/ error of service provider. Penalizing for same is injustice.

I was conveyed the problem to the service provider through email on the same day. But they are replied negatively by saying that once international roaming charges can't be refunded after two days.

I am also again asked them, if due to their technical problems, every month my mobile activated for international roaming, then they will deduct my balance every month / day.

But after elapse of two days no reply received.
