Airtel Prepaid GPRS
GPRS wrong amount deduction

I have my mobile number 8750027860 with internet GPRS connection of 98 rupees pack and i am using this facility from last one year with no problem but since last week my amount is regularly deducted and when i called customer care they told me you are downloading mp3 from site which is not free

let me tell you i am using that site from last one year and still there was not deduction (with 98 rupees internet pack) from my airtel amount but since last week my amount deducted with 40, 26 and 6 rupees approximately.

I requested customer care dept to look in the issue but there is same response.

Kindly take immediate action and let me know the problem and why my amount is deducted from my account.

Call me on 8750027860
