Airtel — Deduction from my main account

Address:

Dharwad, Karnataka

today morning about 11;30 am recharge airtel 3G (1GB 154rs) . after confirmation message, started using mobile data for checking purpose ( i had very worst experience with airtel from last 3 months 200-250 rs losses ) turn off the mobile data, they had deducted 54 rs from my main balance .instead of data balance . immediately called customer care asked the details .they were given irrelevant answers and wanted to confirm one more thing last month i recharged 1gb 2G data it will expire on[protected] and data remaining was 1.56MB when i checked in the morning after that am turn off the data .customer care telling that am browsed more than limit and i asked if i consumed more data how come its showing 1.56 MB remaining, after this they started acting smartly that they will refund only 30rs .if am agree he will pay otherwise disconnect the call.as a reputed network i didn't expected .so i need a permanent solution for balance deduction by airtel .
