I used to have 1 Mbps Unlimited plan (Rs.1874 p/m including taxes.) which had a FUP limit of 100 gb. A few months ago, Airtel upgraded the speed to 2Mbps and downgraded the FUP limit to 30 Gb. The cost was the same.Now, when I check the plans for my region Airtel advertises that the 2 Mbps plan with 30 Gb limit costs only Rs.1299 per month! I don't know when this new pricing was announced but I've been getting charged Rs.1874 p/m till now for a service that Airtel advertises as costing only Rs.1299 p/m. I can only brand this practice as robbery considering Airtel never fails to slap Rs.100 fine when I miss paying my bill by a day but fails to update my plan's pricing.Has something like this happened to anyone else ? What's the best way (if any) to resolve this matter ?
