Airtel — excessive billing amount

Address:

110057

I am using my airtel number [protected] only for voice calls on international roaming in syria from last two days. The total usage must not exceed 40 to 45 minutes of outgoing or incoming calls. However, i have been charged with rs 21000 in last two days. Please check your records. It is not possible for such huge amount. No services should stop on my number. I'll be using the same number for another 10 months in syria. I cant pay such huge amount without any valid usage of number. Please check the same at your end and reduce the billing amount.
Thank you
