Airtel
Gprs Billing

I was using mobile office gprs wherein i was awarded 100 mb free for 399 bugs monthly but beyond that the scheme says some 10 kb 10 ps or 5 ps something which exceeds beyond the limit and i received a bill of 3500.. My regret is that for prepaid customers they provide unlimited usage with 7 or 15 rs daily den why are post paid customers given this step brotherly treatment...
