I have a Airtel Prepaid plan and have subscribed to "StdPlan198" plan but I am still being charged every time I use internet. This was not the case earlier and started suddenly. I know that 30 days are not over after I purchased this plan. Anyone else is facing this problem or has faced it before? Any solutions?Below is what is shown under manager services - 3GPlanName😛re_StdPlan198UsedVolume:18 bytesExpiryDate:2012-12-14T05:54:55
