Airtel — excessive billing by airtel on selected international data roaming

Address:

620021

Please refer to airel bill no[protected] dated 9th june 2018 for rs 26, 499.26,
I have spoken to airtel customer executive multiple times regarding excess billing amount and also sent a mail to airtel in this regard.

While going through bills it has been observed that the charges levied by airtel for usage of mobile data in international roaming on 7th may 2018 are absolutely wrong, i am working abroad and i carry this sim for my incoming sms only, data is easily available in the place i work and i never needed an international roaming data. I carry this sim since last 4 years and never my monthly bill crossed rs 300.
I have also noticed that you have a fixed a credit limit of rs 4, 200 for me for using mobile services from airtel whereas in this case the billing amount is much more than the credit limit. Although, airtel is claiming that this credit limit is valid only for voice and value added services and international roaming is not covered under this but i have never been informed about this and as a lay man i will only understand the meaning of credit limit that i will not be use the services beyond this limit. The services should have been disconnected when my credit limit crossed the limit and i should have been notified. Kindly ask airtel to revise my billing.
