Airtel — Inflated bill without any alert message

Address: Bangalore, Karnataka

Please treat this email as formal complaint for the Relationship Number - [protected] vide Bill #[protected]. This is the second occurrence of a inflated bill in last three months. I have a postpaid plan with 1000 MB quota of 3G per month, and according to the bill I consumed 1300 MB of data. Due to the excess usage of 300 MB of data I have received 4X times the normal bill. I am not denying that I have not consumed the excess amount of data but the problem is that I didn't received even one alert SMS or an email from airtel regarding the crossing of the limit. If airtel can send tens of promotional SMS's per day, why was it not able to send one alert SMS to its loyal customer. I understand that there is a stiff competition among telecom companies with low profit margin, but I don't expect Airtel to resort to these unethical practises. This is the second time the bill is inflated and this time I am not going sit mute for this day light robbery. Please do the needful.
